Fuel pump of the power supply system (VW Passat B2)

The fuel pump is secured with two nuts through a heat-insulating gasket and a sealing ring. The pump body and cover are non-separable, i.e. the pump cannot be repaired and is replaced in case of failure.

Checking the fuel supply pressure of the fuel pump

Connect the pressure gauge hoses to the fuel pump and carburetor.

Start the engine and measure the fuel supply pressure, which at idle should be within 0.20-0.25 kg/cm².

The pressure at the fuel pump outlet is not regulated. If the pressure drops below the permissible value, replace the fuel pump.
