Replacing the coarse filter on a VAZ 2110

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.

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

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.

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!

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.

Replacing the fuel pump mesh for VAZ 2110

Have you encountered problems when the car does not move or there is jerking in first gear? There may be several reasons and it would be foolish to start looking for the reasons with the fuel pump; it would be more correct to first pay attention to the condition of the fuel pump mesh. This is a photo report on cleaning or replacing the fuel pump mesh with your own hands .

The procedure for removing and installing the fuel pump mesh will take you no more than 20-30 minutes: 1. Remove the negative terminal from the battery. 2. Unscrew the plastic cover under the rear passenger seat.

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.

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.

If the pressure drops in the fuel system of VAZ 2110-2112 cars with injection engines, the first thing you need to check is two things:

Fuel filter
Fuel pump mesh

As for the first option, if necessary, we replace the VAZ 2110 fuel filter. As for the pump mesh, this is worth talking about separately.

First of all, it’s worth saying that to perform this work you will need the following tool:

The head is 7 mm deep
Ratchet with extension
17 open-end wrench
Screwdriver flat and Phillips

The first step is to relieve the pressure in the fuel system and remove the fuel pump from the tank.

After this, all that remains is to complete the following steps:

Remove the lower part of the pump - container
Use a screwdriver to pry off the mesh body and remove it
If necessary, install a new one

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.

Replacing the mesh on a VAZ 2110-VAZ 2112

Removal:

1) We talked about cars with a 1.5 liter engine above.

2) Now let's talk about 16-valve cars. Remove the pump, take a screwdriver and remove the retaining ring from the guide (often called the pin). There is only one ring, although there are two guides. It is removed as follows: pry it with a screwdriver and move it to the end of the guide in the direction of the blue arrow in the photo until it is completely removed. Now the main thing is not to turn the fuel pump over, otherwise the housing will fly out spontaneously and the hoses may break.

3) The photo below shows two blocks with wires; they need to be disconnected. If you pull with force and they do not give in, then you are doing something wrong and there is a possibility of breaking the clamps. Press the retaining clips and carefully remove them.

4) Grab the top of the fuel pump with your hand and separate the two housings along the guides. Put one housing aside, continue to hold the gas pump in your hands and use a screwdriver to disconnect the mesh. Remove it and replace with a new one.

Installation:

Proceed in the reverse order of removal. Make sure that the part is securely fixed; it should not fall off. We recommend that you take your time and do not install the fuel pump flap with the rear seat cushion, but rather ask an assistant to turn the key in the ignition for about 5 seconds, and you watch to see if gasoline flows from under the fuel pipes. The tightness of the system is mandatory; in case of malfunctions and leaks, replace worn parts with new ones.

Additional video: Attached below is a video using the example of a VAZ 2114 on the topic of today’s article, we recommend you watch it.

Note!

The video below shows the procedure for disconnecting the wire block; if you have difficulties with this, it is useful to watch:

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.

Replacing the fuel pump on a 16-valve VAZ-2112 with your own hands

A gasoline pump is a part of a car that is responsible for supplying fuel from the gasoline tank to the nozzles. For the first time, an electric gasoline pump was invented in the USA in the 70s of the 20th century. In the mid-90s, almost all automakers switched to this system, abandoning the mechanical one. Replacing a gasoline pump on a VAZ-2112 is quite easy and does not require special knowledge or skills.

Video on replacing the fuel pump on front-wheel drive VAZs, including the VAZ-2112:

The video material will tell you how to replace a gasoline pump, and also give some recommendations and tips.

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:

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.

Video instructions for replacing the fuel pump mesh on a VAZ 2110-2112

To clearly show this repair procedure, a photo will clearly not be enough, and that is why I made an accessible description in the form of a video lesson. If you have any questions, ask in the comments to the article or to the video itself. When everything is done, you need to install a new grid and put it in place in the reverse order. The price of this part is no more than 100 rubles in any auto parts store.

Now you can install the fuel pump in place, tighten all the fuel fittings and connect the power plug. Then we pump gasoline a couple of times before starting the engine. We start the engine and check the pump for operation.

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.
