Fuel System - General Information
FUEL SYSTEMComponent Location - 6.0L Diesel:
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 tank.
- circulates fuel under pressure through the fuel filter, the water separator and the pressure regulator to the cylinder head fuel galleries and then to the fuel injectors.
- Excess fuel is returned to the fuel tank through the fuel return hose.
Fuel Filter/Water Separator
The diesel engine is equipped with a fuel filter and water separator assembly. Drain the water from the fuel filter at the recommended maintenance intervals. Refer to the Service Guide for maintenance intervals. If there is water in the fuel an indicator on the instrument panel will alert the operator. When the indicator glows continuously while the engine is running, drain the water from the fuel filter and water separator bowl as soon as possible to prevent damage to the fuel injection system.
