How to measure the pressure in the fuel system?

Most of the units and components in cars of the Lada Samara model line can be changed with your own hands. To do this, just stock up on the necessary tools and purchase a new part. This material describes in detail how to replace a VAZ 2110 fuel pump and its filter element - a mesh. The work is quite simple, since installing a new product does not require an inspection hole or a lift. After studying this material, the reader will learn how to change the fuel pump, when it needs to be done and how to determine that the unit has failed. To make sure that the device has failed, you need to measure its pressure - the article contains several ways to perform this action.

Advice! Many Samara owners install a VAZ 2110 Bosch fuel pump. Despite the higher cost, the imported unit has a long service life, and it is easier to maintain when compared with a standard unit.

Step-by-step process for replacing the fuel pump mesh on a VAZ-2112

In order to dismantle the mesh on the fuel pump, it is necessary to remove the fuel pump from the tank, and to do this we do the following:

We place the car on a flat surface, ensure it is in a stable position and put on the handbrake.
Disconnect the negative terminal from the battery.
Removing the back seat. It can be completely dismantled by unscrewing just two bolts, or simply moved to the side.
Unscrew the bolts that secure the fuel pump hatch.

First, turn off the fuel pump!

Please note - the power is turned off here!

Please note that when dismantling the fuel pipes, there may be a release of pressure in the system, so cover the pipes with an old rag in advance.

When the lines are removed, remove the rubber gaskets and seals from each of them, and then replace them with new ones.

The rubber seal is indicated by the arrow.

The nuts are marked with a red marker.

If the gasket is damaged, replace it.

We remove the fuel pump on a rag.

If any parts and elements in this system show signs of damage or wear, they must be replaced.

Cleaning the fuel pump mesh

If it happens that you do not have the opportunity to purchase a new mesh, and the old one has become unusable, you can simply clean it and below we will tell you how to do this.

There are several ways to carry out this procedure and here are some of them:

The mesh is cleaned by soaking it in a solution of detergents or bath cleaners. To do this, mix them with water at a ratio of 1 to 10 and then leave it there for one hour. When the soaking time is over, simply rinse the mesh under running water.
Using the same solution, rinse an old toothbrush in it and clean the mesh with rotational movements.
If you have a compressor, then it can also be useful during such work.

Please note that after performing such mechanical work on the mesh, inspect it for damage, since the presence of defects makes it impossible to use it in a gas pump.

Fuel coarse mesh in the fuel pump - why is it needed?

The initial cleaning of the fuel is ensured by a mesh mounted on the fuel pump body, and when the car begins to move jerkily and the fuel supply is difficult, first of all you should check the condition of this mesh, because it can be contaminated to such an extent that its initially snow-white color is very difficult to recognize.

Note! The main reason for grid contamination is poor fuel quality!

When to change the screen in the fuel pump?

In order to understand when it is necessary to replace a particular component in the fuel system, and specifically the grid, you need to know about the presence of pressure in the fuel rail. You can learn how to take measurements correctly from this article.

You can also find out about its insignificant condition by the following signs:

When the ignition is turned on, a very prolonged and loud hum , since gasoline is hardly sucked into the system through a clogged mesh. This can significantly reduce the working life of the fuel pump itself and the contamination of the entire fuel system as a whole.
While driving, when switching to third or fourth gear and then pressing the gas pedal, there is no increase in power .
Also, a clogged mesh can cause a loss of speed while the car is moving , since the required amount of fuel simply does not enter the combustion chambers.

Cleaning or replacement?

The filter, which is located in the fuel pump, must be replaced if there is contamination on it, since its price is not high. However, if you find yourself in a situation where it is simply not possible to buy a new element, then you can wash it.

Remember that the effect of cleaning the fuel pump mesh will only be temporary, and replacement should be carried out as soon as possible.

Replacing the fuel pump filter on a VAZ-2110 - On VAZ-2110 cars with an injection system, in addition to the fine fuel filter, there is also a filter mesh located in the gas tank on the fuel pump. The mesh is designed for rough cleaning of fuel. You've already bought the mesh, that's not a problem, now let's change it!

Replacing the fuel pump filter on a VAZ-2110

Replacing the filter mesh on the fuel pump takes about 30 minutes. Let's start with the battery! To do this, you need to remove the negative terminal from the battery. Next you need to remove the rear passenger seat. And now we remove the fuel pump cover by unscrewing just two screws, then carefully disconnect the pump power supply.

Using a 17 wrench, unscrew the fuel hose fittings.

Then use a 7mm socket wrench to unscrew the fuel pump mounting nuts and carefully remove the pump so as not to damage the fuel level sensor float, while the pump cup may remain in the gas tank; it must be removed from the tank.

We remove the mesh from the pump and install a new one, put the pump in the glass and install it in place. We collect everything else in the same sequence.

Many people manage to clean the mesh with toothbrushes, but if it is not changed for a long time, the mesh becomes deformed and breaks due to the corrosive effects of gasoline. It is advisable to change the mesh, especially since the cost of a new mesh is about 60 rubles, which is not expensive.

When replacing the mesh at a service station, car service center or specialized workshop, additional work must be carried out on the pump itself, for example, fine adjustment of the fuel level float. Adjustments are made on a stand, which you don’t have in your garage!

Pump operation and malfunctions

From the name you can understand that the fuel pump supplies fuel from the tank to the engine injectors. Accordingly, if the unit is faulty, then there will be no gasoline injection, and the power unit will not start working. There are options for injector and carburetor. The VAZ 2110 is equipped with an injector; therefore, the fuel pump must be suitable for this system. If the “ten” was modernized by installing a carburetor, then the unit will have to be taken out of stock. The unit is located in the fuel tank - under the left rear door, the electrics go under the rear row seats.

Article on the topic: The starter on the injection VAZ 2110 does not turn?

It is quite simple to understand that there are faults in the pump or its network:

The car won't start. There are many reasons for this malfunction, but before performing a full diagnosis, you need to check whether the pump mesh is clogged or clogged.
There are noticeable jerks in first gear. There are also many options here, but one of them is a non-working fuel pump.

Instructions for replacing the fuel pump mesh on a VAZ 2110

One of the car maintenance operations is replacing the VAZ 2110 fuel pump grid. The procedure is quite simple; you only need knowledge of the procedure for performing the work and a minimum set of several tools. Therefore, it is usually performed by car enthusiasts themselves, without the involvement of service station specialists.

Replacement of the VAZ 2110 fuel pump, its mesh and filter. Signs of malfunction.

Advice! Many Samara owners install a VAZ 2110 Bosch fuel pump. Despite the higher cost, the imported unit has a long service life, and it is easier to maintain when compared with a standard unit.

When to replace

Such minor repairs are carried out as the grid becomes dirty, which happens quite quickly, given the quality of domestic fuel. The correct approach is to change all consumables at the same time, guided by the frequency of pouring new oil into the engine.

During this procedure, you can replace the air and oil filters, as well as the fuel pump mesh. If you make it a habit to change this mesh only after it is completely clogged, the pump will constantly work with increased load, as a result of which repair or even replacement of the VAZ 2110 fuel pump will quickly be required.

The first sign of a faulty fuel pump is the engine refuses to start. After turning on the ignition, you can hear a slight buzzing sound of the operating gasoline supply device, which stops after it creates the necessary fuel pressure in the system.

If after this the car engine does not start or even the sound of the VAZ 2110 pump cannot be heard, then you need to check the presence of gasoline pressure in the line. This is done using the bleed valve on the ramp. The verification procedure will be discussed below. If there is no fuel, it becomes clear that the fuel pump is not working or its screen is clogged.

How to measure the pressure in the fuel system?

Screw on the meter hose

The easiest way to measure pressure is with a special device - a pressure gauge. The kit also includes an adapter and drain. Pressure can be determined using an air pressure gauge. This device is present in almost every motorist, as it is used to measure tire pressure. A normally functioning pump in a VAZ 2110 should have a reading of 2.8-3.2 atm. You need to connect the pressure gauge and check what the indicator is with the engine not running, but with the fuel pump on. It must be no lower than 2.8 atm.

Description of the work

The location of the VAZ 2110 injector fuel pump is in the gas tank located under the bottom of the car, in the area of the rear seat. It is accessible from the cabin, so no inspection holes or other additional devices are required. Only tools needed:

open-end wrench 13 and 17 mm;
Phillips screwdriver;
7 mm tubular socket wrench.

Instead of a long 7 mm tubular wrench, you can use a small open-end wrench, but this will be inconvenient and take more time. Before starting repairs, you should completely remove and pull out the rear seat to gain access to the gas tank. Two more preliminary operations that are done in the engine compartment.

Loosen the nut securing it to the negative terminal of the battery, remove the clamp along with the wire.
Relieve pressure from the fuel line. At the end of the ramp, near the outer nozzles, there is a bleed valve with a rubber cap on it. Having removed it and substituted a plastic cup, you need to press the valve stem. Fuel will leak out from there and the pressure in the system will drop.

Under the bottom of the rear seat there is a square hatch that provides access to the gas tank; it will need to be removed. The subsequent disassembly diagram looks like this.

Using a Phillips screwdriver, unscrew the 2 screws securing the hatch cover, remove it and put it aside.
Disconnect the fuel pump electric drive connector and move it out of the way.
Using an open-end wrench, loosen and unscrew the 2 nuts that secure the fuel line pipes to the fuel pump fittings.
Pull the tubes out of their sockets. The round rubber rings attached to their ends must be removed and replaced with new ones, since they are designed for one-time use.
Using a long tubular wrench, unscrew the 8 nuts that hold the flat flange that presses the VAZ 2110 fuel pump to the bottom surface. Remove the flange from the studs.
There is a rubber gasket on the mounting studs under the clamping part of the body. The latter must be removed from the studs, otherwise it will not make it possible to pull out the fuel supply device. Then carefully remove the fuel pump from the tank cavity along with the float. If the rubber gasket is worn out, then it is better to replace it too.

When removing the unit, gasoline will flow out of it, so you should place a rag underneath and quickly move the fuel pump out, placing it above a wide pan. The mesh is located at the end of the suction tube and is secured with a plastic ring. You can remove it manually.

If the ring is strongly stuck to the tube, it is recommended to pry it off, for example, with a flat screwdriver. Next, a new mesh is placed and fixed by pressing the hand all the way. Now you can reassemble, which is done in reverse order. There is an arrow stamped on the top of the unit; it should point to the rear of the car.

We recommend tightening all connections with little force. To avoid distortion when tightening the 8 nuts of the clamping flange, a star tightening pattern is used.

If it is necessary to replace the fuel pump on a VAZ tenth model or repair it, then the system is disassembled as described. When replacing, you need to remove the float and level sensor from the unit and move them to the new pump. The entire procedure, if performed in conjunction with replacing other consumables, will take you no more than half an hour.

Replacing the fuel pump mesh on a VAZ 2110, VAZ 2111, VAZ 2112

Welcome! The fuel pump mesh is also a fuel coarse filter, it is located in the fuel pump itself and therefore, before the fuel pump starts pumping gasoline into the engine, it will therefore pass through this filter and be cleaned, then the gasoline goes through the fuel pipes and on its way ( In the area of the gas tank) there is another filter, the so-called fine filter, which cleans gasoline from small particles of dirt and which retains water (Water can kill a car engine, and it can get into it due to low-quality fuel that is spilled at cheap gas stations) and after the fuel passes through both of these filters, it will be supplied to the engine, and if excess is supplied, then the excess will fly back into the tank thanks to the fuel pressure regulator and thus gasoline circulates through the fuel system, but over time any filter comes becomes unusable and becomes clogged, which causes the car to twitch, it develops dips and unstable idling, but this is not the worst thing, and the worst thing is that if the coarse filter is heavily contaminated, the fuel pump begins to wear out and runs out very quickly out of order, so periodically the fuel pump still needs to be removed and this filter in it needs to be changed, especially since it costs a penny, but still some people manage to clean it and reuse it, we don’t recommend you do this, because all the dirt from it goes nowhere will not go away and still small particles will remain.

Instructions for replacing the fuel pump mesh on Chevrolet, ZAZ and Daewoo Lanos, Sens and Chance

It should be noted right away that the resource of this filter element ranges from 50 to 100 thousand kilometers. It all depends on the quality of the gasoline being poured into the tank, but you can refuel once unsuccessfully and, at best, end up having to replace the filter, and in the worst case, you will have to change the fuel pump.

Next, we’ll look at how to replace the Lanos fuel pump mesh yourself, and what you’ll need for this. When carrying out the work, you will need a minimum set of tools, consisting of a flat or slotted screwdriver, steel wire and a hair dryer. To replace the mesh, you will need to remove the entire fuel pump module. How to do this yourself is described in detail in the material on removing the gas tank or instructions for replacing the Lanos fuel pump. The process of dismantling the fuel pump assembly with the mesh must begin by disconnecting the negative terminal of the battery.

After the fuel pump module assembly is removed from the mounting hole of the tank, we proceed to further steps to replace the strainer:

After removing the pump, there will be some fuel left in it, which can be drained back into the tank or container by turning it upside down
We place the entire mechanism assembly on a clean cloth or newspaper, and proceed to replacing the mesh
The first step is to dismantle the float, for which the plastic clip in the shape of the letter “C” is removed. To remove the clip, you need to squeeze it and remove it from its seat.
To get to the fuel pump coarse filter, you should remove the top cover of the plastic flask. It is attached using three protruding slots, which you need to press with a screwdriver.
Before removing the top cap of the flask, you need to disconnect the power supply connector for the fuel level sensor. This sensor is attached to the outer flask (also called a glass)
Next, we move on to dismantling the inner flask with the fuel pump, since the mesh is attached specifically to it. You can dismantle the inner flask using strong steel wire, from which you need to make a hook. An example of such a hook is shown in the photo below.
The hook is needed to dismantle the inner flask (with the fuel pump), to which the mesh is attached. This flask is fixed using an internal protrusion along the circumference on the outer flask. The photo below shows a protrusion in the inner part of the outer flask, through which the fuel pump bracket with filter is fixed
To simplify the process of dismantling the inner flask, it is necessary to heat the walls of the outer bowl with a hairdryer. This will lead to its expansion, which will allow you to easily and quickly remove the flask (it is important not to overdo it with a hairdryer)
Using a hook, you need to hook onto the plastic protrusion on the inner flask and pull towards you (moderately). To increase the effectiveness of actions, efforts should be made alternately at several points. As a result, the inner flask with the fuel pump and the mesh located at the bottom is removed
It is this mesh that needs to be replaced, having previously assessed its condition
In 100% of cases, the inside of the outer flask will have contaminants that should be removed
Let's start removing the mesh, for which you first need to remove the locking ring (washer) by prying it off with a screwdriver
The old filter is removed, replaced by a new one, and secured with a retaining ring. It is recommended to purchase a new ring, since when it is removed, the quality of fixation has significantly decreased. If you install an old ring, there is a high probability that the mesh may come loose during use.
We install the Lanos gas tank mesh in place and carry out the assembly in the reverse order

The procedure for replacing the gas tank mesh is not difficult, but it is very responsible, since the work is carried out with parts that are coated with highly flammable substances.

After assembling and installing the fuel pump with the new element in place, you can put the negative terminal on the battery and turn on the ignition. When the pump pumps gasoline and turns off, you can start the engine. This completes the process of replacing the fuel pump mesh.

This is interesting! Two types of fuel pump modules TA and TG were installed on Lanos. The principle of replacing the mesh on TG type devices is discussed above. Blocks of the TA type differ in that the mesh on them is located on the outside. You can read more about the differences between the modules here.

How to replace the fuel pump mesh on a VAZ 2110-VAZ 2112?

Removal: 1) About a car with a 1.5 liter engine, we already said a little higher how the mesh is changed on them, let’s remember again, first the glass is removed from the pump and put aside, then you take a screwdriver and use it to remove the mesh by prying it off and that’s it, At this point, the mesh has been replaced, about the installation, read below, but before you do all this, you need to remove the fuel pump itself, and not all people know how to remove it, we described the detailed removal process in the article entitled: “Replacing the fuel pump on cars.”

2) Now let's talk about sixteen valve cars, let's say you've already removed the pump from the car and it's in your hands and you need to replace the mesh, first you'll need to stock up on a screwdriver and use it to remove the retaining ring from the guide (Some people also call it a pin), this ring only one, although there are two guides (In the photo below this ring is indicated by an arrow for clarity, it is removed as follows, first picked up with a screwdriver and then guided to the very end of the guide in the direction where the blue arrow is shown and it is guided until it is completely will be removed), after which your main task is not to turn the fuel pump over, otherwise the housing will spontaneously fly out and the hoses may break.

3) Let's go further and now you will need to disconnect two wire blocks, both are shown with arrows in the photographs below for clarity, they are easily disconnected and if you pull with force and they do not disconnect, then you are doing something wrong and there is a possibility that you will break the clamps this way , so look for these pads and, by pressing on the latches that hold them, carefully disconnect them (you will need to press some of the latches, bend some, both pads are attached differently, you can clearly see how to disconnect them in the video clip which is located at the very end of the article ).

4) And now that the locking ring has been removed, both pads are disconnected, you can take the upper part of the fuel pump with your hand and separate the two housings from each other along the guides; when they are separated, put one housing aside, and continue to hold the fuel pump housing in your hands and do exactly the same Using a screwdriver, disconnect the mesh and remove it, replacing it with a new one.

We change the mesh on the fuel pump 16 valve VAZ-2112 with our own hands

The flawless operation of any car is ensured by its engine, and its operation, in turn, is simply impossible without clean and high-quality gasoline entering its channels. The main unit for supplying fuel to the engine is, without a doubt, the gas pump, which delivers it from the car’s gas tank through the fuel channels to the combustion chambers. Therefore, it is very important that all gasoline passing through is clean and of high quality.

The video describes in detail and shows how to remove, diagnose and, if necessary, replace the fuel pump mesh on a VAZ-2112.

How often should the fuel filter be changed?

The frequency of routine filter replacement is primarily determined by the vehicle manufacturer. For some manufacturers this is 30,000 km, for others - 120,000 km. Moreover, frequent replacements are usually recommended by manufacturers who place the filter outside the fuel tank. You should only change the fuel filter ahead of schedule if you are sure that foreign mechanical particles or a large amount of water have entered the tank. In this case, you should also rinse the tank and possibly replace the fuel pump.

Diesel engine fuel filters have the most difficult time in winter: after all, thickened fuel must pass through the filter material. That is why it is better to carry out preventive filter replacement on a diesel car in the fall. This is due to the fact that the filter capacity, already reduced by clogging with solid particles, will be insufficient to pass the cold, thickened fuel.

Step-by-step process for replacing the fuel pump mesh on a VAZ-2112

In order to dismantle the mesh on the fuel pump, it is necessary to remove the fuel pump from the tank, and to do this we do the following:

We place the car on a flat surface, ensure it is in a stable position and put on the handbrake.
Disconnect the negative terminal from the battery.
Removing the back seat. It can be completely dismantled by unscrewing just two bolts, or simply moved to the side.
Unscrew the bolts that secure the fuel pump hatch.

First, turn off the fuel pump!

When access to it is open, you can see the power and fuel supply connectors.
First of all, disconnect the power supply block.
Next, we disconnect the fitting through which fuel is supplied to the system and take it to the side.

Please note - the power is turned off here!

We do the same with the fuel drain line.

Please note that when dismantling the fuel pipes, there may be a release of pressure in the system, so cover the pipes with an old rag in advance.

When the lines are removed, remove the rubber gaskets and seals from each of them, and then replace them with new ones.

The rubber seal is indicated by the arrow.

When nothing is in the way, unscrew the 8 bolts located around the fuel pump cover.

The nuts are marked with a red marker.

Remove the unscrewed ring and gasket.

If the gasket is damaged, replace it.

When access to the fuel pump is open, take it out of the gas tank. During these actions, be careful, since the float located on its body is a very sensitive element.

We remove the fuel pump on a rag.

When the fuel pump is removed, you will notice a mesh underneath it, which is a kind of coarse filter.

Dirty fuel pump screen.

Replace it with a new one and do all the work in the reverse order of removal. At the same time, do not forget to replace the o-rings on the fuel line and check the gasket on the o-ring of the fuel pump itself.

The difference between the old grid and the new one.

If any parts and elements in this system show signs of damage or wear, they must be replaced.

Cleaning the fuel pump mesh

If it happens that you do not have the opportunity to purchase a new mesh, and the old one has become unusable, you can simply clean it and below we will tell you how to do this.

There are several ways to carry out this procedure and here are some of them:

The mesh is cleaned by soaking it in a solution of detergents or bath cleaners. To do this, mix them with water at a ratio of 1 to 10 and then leave it there for one hour. When the soaking time is over, simply rinse the mesh under running water.

Using the same solution, rinse an old toothbrush in it and clean the mesh with rotational movements.

If you have a compressor, then it can also be useful during such work.

Please note that after performing such mechanical work on the mesh, inspect it for damage, since the presence of defects makes it impossible to use it in a gas pump.

Fuel coarse mesh in the fuel pump - why is it needed?

Note! The main reason for grid contamination is poor fuel quality!

When to change the screen in the fuel pump?

You can also find out about its insignificant condition by the following signs:

a very prolonged and loud hum occurs . since gasoline is difficult to absorb into the system through a clogged mesh. This can significantly reduce the working life of the fuel pump itself and the contamination of the entire fuel system as a whole.
While driving, when switching to third or fourth gear and then pressing the gas pedal, there is no increase in power .
Also, a clogged mesh can cause a loss of speed while the car is moving . since the required amount of fuel simply does not enter the combustion chambers.

When to change the fuel pump mesh Lanos, Sense and Chance

Any filter becomes dirty over time, and this also applies to the mesh installed at the inlet of the gas pump. When the element becomes clogged, there is a decrease in its throughput, resulting in a decrease in the amount of intake fuel. Reduced gasoline absorption has a negative effect not only on the fuel pump itself, but also on the functioning of the engine. A clogged mesh of the Lanos suction device leads to the following consequences:

The load on the pump electric motor increases, causing it to heat up more. This reduces the service life of the device
The absorption of the amount of fuel decreases, which ultimately leads to a decrease in the quality of cooling of the pump electric motor.
The pressure in the fuel line decreases, which negatively affects the functioning of the internal combustion engine

The main signs of a clogged fuel pump filter on Lanos are:

Problem starting the engine due to low pressure in the fuel line
The engine does not start at all if the filter is heavily clogged
When the car moves, jerking and jerking appears, indicating problems with the fuel supply

If the above symptoms occur on Lanos, it is necessary to resort to replacing the part. Every driver can cope with this, but the biggest drawback of the process of replacing the fuel pump grid on Lanos is that this will require dismantling the entire module.

This is interesting!
Some drivers prefer to clean it instead of replacing the mesh. This is not a rational approach to such an event, since it is impossible to clean the element to perfect condition. However, this method is suitable when the engine does not start due to a clogged filter mesh, but you still need to get home or to a car service center.
