Replacing the fuel filter on a Lada Vesta with your own hands

Fuel supply system design

The fuel supply system of the Lada Vesta car consists of 5 parts:

• Gas tank with filling pipe. The gasoline tank is made of compressed plastic and is attached to the bottom of the car with two metal clamps. The filler neck is located on the right side of the Vesta. The plug has 2 valve mechanisms. One ensures the release of excess pressure created in the tank due to thermal expansion. The other serves to intake air, which fills the container when the liquid level in the gas tank decreases.
• Fuel module. Provides pumping of gasoline into the fuel rail. Consists of a fuel pump, bypass valve, gasoline level sensor and filter device.
• Injectors. Located on the ramp. Fuel is injected into the internal combustion chamber.
• Adsorber. The main component of the vapor recovery system. Located on the right side of the car, near the front fender. Equipped with a purge valve.
• Pipelines. Serve to transport fuel and gases between components of the fuel supply system.

Unlike the design of the unit installed on previous AvtoVAZ models, the Vesta fuel filter is not portable. According to the manufacturer, the cleaner's lifespan is sufficient for the entire life of the vehicle. Sometimes cases of low-quality gasoline are poured in, which forces owners to replace the mesh in the Vesta filter.

In an official car service, they do not change individual components, but install a new unit. The catalog number of the fuel pump is 21800113900900. The cost of a new original unit averages 6,000 rubles.

When to change the fuel filter on Vesta

According to the manufacturer, the service life of the fine gasket is equal to the service life of the fuel pump. The fuel pump has a resource of 180 thousand kilometers. Photos on the Internet show dirty filter elements with more modest mileage figures.

On forums, car owners say that they change the fuel filter on their Vesta every 30-40 thousand km. The frequency of replacement is directly affected by the purity of the fuel used. When refueling at a suspicious gas station, the filter elements may become clogged within the first kilometers of driving.

Signs that replacement is needed

You can understand that the filtration device is clogged by some characteristic features of the machine’s behavior. These include:

• fuel pump noise;
• increased fuel consumption;
• reduction in engine power;
• car jerks when driving;
• floating idle speed;
• Difficulty starting the engine.

When the “Check Engine” light comes on and subsequent computer diagnostics, a clogged fuel filter displays error P0171.

These signs may also indicate other problems. But if the filter device was changed a long time ago, then you can start eliminating the problems by replacing it.

Frequency of replacing the fuel filter

According to the official statements of the manufacturer, the fuel module with filters is designed for the entire service life of the Lada Vesta car and does not require periodic replacement. At the same time, drivers note that in domestic realities the unit becomes clogged extremely quickly. So the mesh may need to be replaced after a mileage of 30-50 thousand km. The fine filter lasts longer. It gets clogged when it reaches 100 thousand km.

Symptoms of the need to replace filters are:

• jerks when the car moves;
• Unstable engine operation during intense acceleration;
• noise from the fuel pump;
• difficulty starting the engine;
• decrease in dynamics;
• deterioration in motor load perception.

Self-replacement of the coarse fuel filtration device

The process of removing the gasoline pre-purification mesh on Vesta is more complicated than dismantling the filter on AvtoVAZ cars of other models. Difficulties arise from the fact that the unit is built into the fuel pump. A flathead screwdriver may be needed when working to remove the fuel pump.

How to remove

Step-by-step instructions on how to remove the Vesta fuel filter:

1. Remove the back cushion of the sofa. The seat is secured with latches at the front and hooks at the back. Remove the interior soundproofing gasket to provide access to the pump cover.
2. Rotate the cover protecting the fuel pump and remove it.
3. Vacuum and wipe everything thoroughly so that dust and small debris do not get into the gas tank.
4. Disconnect the fuel pump power terminal.
5. Start the car and let it run until it stalls.
6. Remove the terminal from the battery.
7. Disconnect the fuel line.
8. Turn the fuel pump retaining ring counterclockwise and remove it.
9. Remove the element in the plastic case. You need to pull out the knot carefully, at a slight angle. Otherwise, the float sensor that determines the fuel level may be damaged.
10. Carefully pull the lower part of the pump, where the Lada Vesta fuel filter is located, and remove it.
11. Disconnect the drain pipe.
12. Remove all the springs from the glass, marking which part was on which guide.
13. Unclip the 3 latches and remove the fuel module.
14. Pry up the spring holding the mesh and remove the coarse cleaning element.

Getting to the place where the fuel filter is located in the Vesta is quite difficult. You need to remove the components of the assembly very carefully, otherwise the process of replacing the mesh will result in the purchase of a new fuel pump.

How to install a new one

The fuel pump is assembled and installed in the reverse order. After completing the work, you need to bleed the fuel supply system. To do this, insert the ignition key into the lock and turn it a couple of times without starting the car. Then the car is started.

This method was tried by Drayvovite walla03. The design of the Lada XRAY implies the presence of a dummy under the hood of the car. Therefore, in its place you can put a VAZ filter, which costs about 200 rubles.

To independently install a removable fuel filter on the X-Ray, you need to turn off the engine, then unscrew the filter and remove the quick-release fuel pipes, and then put the purchased filter in place of the dummy.

Of course, it’s difficult to talk about the effect, but it definitely won’t get any worse. In addition, after completion of 15,000 km, the installed element was replaced. An inspection showed that there were contaminants inside, even with a standard filter in the gas tank.

As you can see, self-installation of a removable fuel filter on Lada Vesta and X-Ray generally pays off. In addition, the cost of such modifications is low, and it takes little time.
