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.

Faults in which the fuel pump module is repaired:

  • - pressure regulator failure;
  • - failure of the fuel pump;
  • - clogging or damage to the coarse filter;
  • - failure or incorrect operation of the fuel gauge sensor.

Symptoms of a fuel pump malfunction are a decrease in vehicle power and dynamics, dips in acceleration mode, unstable engine idling.

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, unrefined 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 level of fuel in the tank, while the reserve fuel light is on.

Because the electric pump is cooled by the fuel in the tank.

To remove the fuel pump module:
