The fuel system for the direct injection turbo (DIT) diesel:

• is controlled by the powertrain control module (PCM).
• utilizes an electric, frame-mounted fuel pump.
• incorporates a fuel filter and water separator assembly.

The electric fuel pump:

• draws fuel from the fuel tank.
• circulates fuel under pressure through the fuel filter and water separator and the pressure regulator to the cylinder head fuel galleries and to the fuel injectors.

Excess fuel is returned to the fuel tank through the fuel return hose.
