The major components of the V6 3.0L SC (Supercharged) fuel system comprises of a fuel tank, a fuel pump module, a fuel filler assembly and two fuel level sensors.

The V6 3.0L SC fuel system uses a returnless fuel system which comprises a fuel pump mounted in the fuel tank to deliver fuel at a variable flow and pressure to the engine mounted HP (high pressure) fuel pumps which supply fuel to the fuel rails and to all the fuel injectors.

The fuel pump operation is regulated by a FPDM (Fuel Pump Driver Module) which is controlled by the ECM (Engine Control Module). The FPDM regulates the flow and pressure supplied by controlling the operation of the fuel pump using a PWM (Pulse Width Modulation) output.

The fuel rails and the injectors are described in Fuel Charging and Controls - V6 3.0L SC
