Fuel Tank and Lines

FUEL TANK AND LINES

The diesel fuel system consists of:
- the fuel tank.
- The midship fuel tank is mounted to the LH frame side rail.
- The aft-of-axle fuel tank is mounted between the side rails.

- a fuel tank filler pipe without a restrictor plate.
- a threaded fuel tank filler cap.
- the fuel conditioning module:
- contains the fuel filter and water separator.
- has the fuel pump mounted in the top.
- has an internally mounted fuel warmer (not serviced separately).
- contains a pressure relief valve for overpressure protection in the event of restricted flow.

- fuel tubes.

The fuel pump is controlled by the fuel pump PCM relay. Electrical power to the fuel pump is provided through the inertia switch (IFS switch). The fuel recirculation/filter unit assists in preventing the fuel from gelling in the lines during cold weather operations.
