The diesel fuel system contains:
- a fuel tank. There are 2 types available:
- a midship fuel tank (mounted to the LH frame side rail).
- an aft-of-axle fuel tank (mounted at the rear of the frame between the side rails).
- a fuel tank filler pipe without a restrictor plate.
- fuel tubes.
- a one-fourth turn fuel tank filler cap (green for ultra low sulfur diesel).
- a fuel conditioning module that:
- has a fuel filter and water separator to protect the fuel injectors.
- has an in-line FP which provides pressurized fuel to the engine.
- is frame mounted.
- the fuel tank selector valve.
- frame-mounted in-line valve, electronically controlled by a switch, which allows fuel to be drawn from either fuel tank.
- an IFS switch.
- a vapor tube (midship fuel tank).
The fuel tank stores the liquid fuel. The FP, located in the fuel conditioning module is controlled by the PCM. Electrical power to the FP is provided through the IFS switch. The fuel supply tubes route fuel from the fuel tank to the engine and the fuel return tubes route unused fuel from the engine back to the fuel tank.
