Fuel Tank And Lines - V6 S/C 3.0L Petrol (G2278767): Overview: Notes

The fuel system is divided into 2 sub systems:

• Low Pressure (LP) system
• High Pressure (HP) system
  • For additional information, refer to: FUEL CHARGING AND CONTROLS

The LP fuel system features the following components:

• Fuel Tank - Molded plastic saddle type
• Fuel pump module (with integral LP fuel pump)
• Fuel level sensor (quantity 2)
• Low fuel pressure sensor
• Fuel lines
• Fuel Pump Driver Module (FPDM).

The fuel system uses an electronically controlled fuel system. There is no separate fuel line to return fuel the tank. The system allows the LP fuel pump to deliver fuel to the HP fuel pumps, dependent on engine demand.

The LP fuel pump also supplies fuel to 2 jet pumps, that pump fuel from either side of the fuel tank into the swirl pot. The jet pumps make sure that there is sufficient fuel in the swirl pot for the LP fuel pump.

The emissions system is described in 'Engine Emission Control'.
