Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Electric Fuel Pump
The electric fuel pump is located in the fuel delivery module. It is mounted with and connected to the fuel sender unit.
The fuel pump is an electric pump controlled by the engine control module (ECM) through the fuel pump relay. The motor rotates an impeller within the pump assembly. This causes fuel within the fuel tank to be drawn into the fuel inlet port. Fuel is pumped out to fuel injectors under pressure through the fuel pipes and hoses.
Fuel pressure is retained when the fuel pump is not running by means of a one-way check valve located within the pump.
