The fuel system consists of:
- the fuel tank.
- The midship fuel tank is between the frame side rails on the left hand side.
- The aft of axle fuel tank is mounted between the side rails.
- a fuel tank filler pipe which contains a restrictor plate to permit only unleaded fuel to be pumped into the fuel tank.
- a 1/8 turn fuel tank filler cap.
- a fuel filter providing filtration to protect the fuel injectors.
- fuel lines.
- a check valve which maintains system pressure after the pump is shut off.
- a fuel pressure regulator.
- a fuel pump and sender assembly which provides pressurized fuel to the engine and a signal to indicate fuel level to the instrument cluster, and contains:
- a serviceable fuel sender
- an inlet filter
- a pressure relief valve for overpressure protection in the event of restricted flow.

The fuel pump is controlled by the fuel pump powertrain control module relay. Electrical power to the fuel pump is provided through the Inertia Fuel Shutoff Switch (IFS Switch).
