Fuel Pump
The
fuel pump is mounted in the fuel sender assembly reservoir. The fuel pump is an electric high-pressure pump. Fuel is pumped to the
fuel meter body at a specified flow and pressure. Excess fuel from the fuel meter body assembly returns to the
fuel tank through the fuel return pipe. The fuel pump delivers a constant flow of fuel to the engine even during low fuel conditions and aggressive vehicle maneuvers. The Powertrain Control Module
(PCM) controls the electric fuel pump operation through a
fuel pump relay. The fuel pump flex pipe acts to dampen the fuel pulses and noise generated by the fuel pump.
