Fuel System Component Location - Midship Fuel Tank, Part 2:

The 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 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 fuel pressure regulator.
^ a fuel pump which provides pressurized fuel to the engine and contains:
- a serviceable fuel sender
- an inlet filter
- a check valve which maintains system pressure after the pump is shut off.
- 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).
