FUEL TANK AND LINES

Fuel System Component - Midship Fuel Tank:

Fuel System Component Location - Aft-of-Axle Tank:

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 powertrain control module (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.
