We remove the fuel module to replace the fuel filter, as well as in case of malfunction of the module parts

The module structurally consists of an electric pump, a fuel level sensor, a pressure regulator and a coarse filter.

Malfunctions in which the fuel pump module is repaired:

- malfunction of the pressure regulator;

- fuel pump failure;

- clogging or damage to the coarse filter;

- failure or incorrect operation of the fuel level indicator sensor.

Symptoms of a fuel pump malfunction are a decrease in the power and dynamics of the car, failures in acceleration mode, unstable engine operation in idle mode.

A sign of deterioration in the operation of the fuel pump is a "howling" or a constant unpleasant hum, with excessive wear of the pump part due to operation with poor, uncleaned gasoline.

The smallest mechanical impurities contained in such fuel contribute to the wear of the rubbing surfaces of the pump part.

The reason for the rapid wear of the pump is also driving with a low fuel level in the tank, with the backup fuel remaining light on. Because the electric pump is cooled by the fuel in the tank.

To remove the fuel pump module:

We are preparing the car for the task.

We install all the parts in reverse order.

During the installation of the module, we monitor the correct location of the O-ring.

Installing the module in the tank

When installing, we orient the fuel module so that the arrow on its lid is located opposite the arrow on the tank.

We press on top of the module cover and screw the pressure ring on the neck of the fuel tank until the module cover is tightly pressed against the neck.

Then we turn the pressure ring to the position where the arrow 3 on the ring is located opposite the arrows 1 and 2.

We put the tip of the fuel tube on the fitting of the module cover until the latches click.

After installing the module, turn on the ignition and check the tightness of the connections.
