Replacing the fuel pump mesh for a VAZ 2110 injector 16 valves video

Replacing the VAZ 2110 fuel pump filter is a pressing problem for many vehicle drivers today. In the event that a motorist drives with clogged filters, there is a very high probability that the fuel pump will simply break down and stop pumping fuel to the engine. For this reason, replacing a VAZ 2110 gas filter is an important and responsible matter.

Different filters are used in the fuel supply systems of carburetor and injection engines.

Gasoline for a carburetor engine passes through a fine filter installed in front of the fuel pump.

This non-separable disposable unit is assembled in a transparent plastic case, thanks to which the condition of the paper filter element can be assessed visually. The filter is the same as in all carburetor cars. In addition to this, mesh types of cleaning the fuel intake, fuel pump and carburetor are guarding the purity of gasoline.

The filter installed in the power supply system of injection engines is also made of paper. But due to the fact that it works under high pressure, it is assembled in a non-separable metal case.

The tenth VAZ model was supposed to be a sedan based on Samara, which later became the “ninety-ninth”. In fact, the index 2110 received a second-generation front-wheel drive car - a car without a proper name, which everyone knows as a “ten”.

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:

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.

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.

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.

Selecting a fine filter

The abundance of consumables on the market makes it difficult to choose. Surveys show that more than a third of “ten” owners use the BIG brand. The brands SCT, Bosch, Mann and Nevsky have proven themselves well.

“Experts” recommend assessing consumables visually by opening the casing. It is unlikely that such an “examination” makes sense. The differences are not fundamental; they are impossible to see with the naked eye. Universal advice - buy one that you don’t mind spending money on.

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 fuel filters

There are fewer problems with replacement on a carburetor engine. The fine filter is visible when you lift the hood. It is attached to the hose section with ordinary clamps. The arrow on the body indicates the direction of fuel movement: from the fuel pump to the carburetor.

Carburetor, fuel pump and fuel intake strainers require replacement extremely rarely. The manufacturer recommends cleaning them with a hard brush, rinsing them with gasoline or acetone and blowing them with air.

Location of fuel injection engine filters

A coarse strainer protects the inlet of the electric fuel pump located in the fuel tank. To access it, you need to remove the electric fuel pump through the hatch under the rear seat.

The designers of the VAZ 2110 placed the fine filter at the rear of the car under the tank.

From the point of view of ease of access, this is not the best solution. To get to the filter you need to drive the car onto an overpass. But do not forget that it works under pressure of several atmospheres. If the housing ruptures, a gasoline spill will cause minimal harm.

Replacement frequency

The manufacturer recommends changing the fine fuel filter of a carburetor engine after 15 thousand kilometers. Engines with injection - half as often, after 30 thousand km.

In practice, motorists usually change filters more often, motivating their actions by the low quality of gasoline at gas stations. They can be understood. Repairing the carburetor or injectors will be more hassle and cost more money than frequent replacement.

As for replacing the electric fuel pump strainer, there is no information about this operation in the list of maintenance work. The manufacturer believes that during the estimated service life of the vehicle, replacement of the electric fuel pump and filter will not be necessary.

However, cars usually last longer than the developers intend for them, so sometimes the coarse filter has to be changed due to interruptions in engine operation.

Filter replacement criteria

Signs of clogging:

• car jerks, which at first only occasionally occur at high speeds, but over time become more frequent and appear at medium speeds;
• reduced engine power (does not pull);
• poor acceleration dynamics (stupid);
• problems with fuel supply when starting the engine; you have to turn the starter for a long time before enough fuel reaches the injectors;
• poor fuel supply when there is little gasoline in the tank;
• black smoke from the exhaust pipe, because due to supply problems the engine runs on a very lean mixture.

If the above symptoms appear, measure the pressure in the fuel supply system (FSS) with a pressure gauge using the fuel rail fitting. It differs for different motors.

When the problem is in the fuel filters (low pressure), the fine filter should first be replaced. If this does not help, wash or replace the electric fuel pump strainer.

Since the launch of the “ten” into production was constantly postponed due to a banal lack of funds, designers and constructors, willy-nilly, had the opportunity to modify the car and “refresh” it taking into account new trends. Perhaps that is why the VAZ-2110 design project was accepted only the third time. In parallel with the improvements in appearance, the content was also changed. In particular, thanks to the forced pause before the car was put into production, VAZ mastered fuel injection, without which entering foreign markets in the early nineties was simply impossible.

Change or clean

The mesh filter can be cleaned, washed and blown, or replaced with a new one. In the first case, the owner will undoubtedly save a certain amount, but will spend more time.

People rarely look into the gas tank. As a rule, if the electric fuel pump grid is clogged, it is completely clogged. Cleaning is possible, but it does not always completely restore the properties of the filter.

The pressure in the system increases after cleaning, but since it is not always possible to completely clean it, there is a high probability of clogging again, and this happens much faster than the first time.

A new strainer for an electric fuel pump is not so expensive that you would have to do extra work for the sake of dubious savings.

Replacing the fuel filter

The fuel supply systems for engines of cars of the “tenth” family differ from each other. Externally, differences are noticeable in the design of the fuel filter. Motors 2111 and 2112 are equipped with filters in a housing with threaded fittings, while in engines 21114 and 21124 the fuel lines are attached with clips.

Engines 2111 and 2112 are equipped with filters in a housing with threaded fittings, while fuel lines are attached to filters on engines 21114 and 21124 with clips

The modification of the installed filter should be clarified by external inspection before purchasing a new one to replace it.

To work you will need:

• open-end wrenches 10, 17 and 19 mm,
• screwdriver,
• container for gasoline (bucket),
• overpass, inspection hole or lift.

Replacing the filter for engines 2111 and 2112

1. Disconnect the battery.
2. Raise the car with a lift.
3. Place the bucket. Carefully unscrew the outlet fitting using 19 and 17 mm wrenches. Collect gasoline leaking from the fuel line into a container.
4. Unscrew the inlet fitting.
5. Loosen the clamp bolt and remove the filter.
6. Install a new one, taking into account the position of the arrow on the housing. It indicates the flow of fuel from the gas tank to the injectors.
7. Tighten the clamp.
8. Connect the fuel lines to the fittings, tighten the threaded connections. Do not use old seals and washers, install fresh ones from the purchased kit.
9. Connect the battery. Start the engine. Make sure it is sealed.

After loosening the clamp, remove the filter. Carefully unscrew the outlet fitting using wrenches 19 and 17. Loosen the clamp with a wrench 10.

Obviously, the appearance of the latest developments from VW and Audi has significantly influenced the image of the “ten”. Like the Eighty, the VAZ-2110 received a barrel-shaped body with soft lines and smooth transitions from volume to volume. The general “slickness” was also facilitated by glued glass, which appeared on the “ten” for the first time on a production car in the CIS.

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.

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:

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.

The rubber seal is indicated by the arrow.

The nuts are marked with a red marker.

If the gasket is damaged, replace it.

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:

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.

How to measure the pressure in the fuel system?

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.
