The fuel pump assembly consists of:
- the electric fuel pump which provides pressurized fuel to the engine.
- the fuel level sensor.
- an inlet filter.
- a check valve which maintains system pressure after the pump is shut off.
- a mechanical fuel pressure regulator with pressure relief for over pressure protection.

The fuel pump is controlled by the Powertrain Control Module (PCM) which energizes the fuel pump relay. Electrical power to the pump is provided through the Inertia Fuel Shutoff Switch (IFS switch).
