OPERATION

The fuel pump module draws the fuel from the swirl pot and drives it to the fuel filter with the integral fuel pressure regulator. The swirl pot prevents the fuel pump from drawing air while cornering with a low level of fuel in the fuel tank with fuel level sensor. The fuel pump is actuated via the fuel pump relay. The fuel pump relay is actuated when it receives a ground signal from the PCM, or ECM, if equipped with a diesel engine.
