Fuel Tank & Lines

The fuel tank and lines consist of the:

• fuel tank.
• fuel tank filler pipe.
• fuel tank filler cap.
• Fuel Pump (FP) module.
• fuel tubes (liquid and vapor).
• fuel filter.
• Fuel Tank Pressure (FTP) sensor.
• Inertia Fuel Shutoff (IFS) switch.

The vehicle:

• has a FP module that supplies fuel under pressure to the fuel rail.
• has an externally mounted fuel filter providing filtration to protect the fuel injectors.
• has fuel tubes (liquid and vapor) mounted on the underside of the vehicle in a bundle.
• has a FTP sensor (part of the fuel vapor tube assembly) that monitors FTP during engine operation and continuously transmits an input signal to the PCM.
• fuel injection rail pressure is controlled by the electronic FP module which is enabled by the PCM.
• has a one-fourth turn vented-type fuel tank filler cap.
• has a fuel tank filler pipe assembly, which cannot be modified in any way and is serviced only by installation of a new fuel tank filler pipe assembly.
• has an IFS switch located in the luggage compartment on the left rear deck lid bracket.
• fuel tank filler pipe contains a restrictor plate to permit only unleaded fuel to be pumped into the fuel tank.
• fuel tank filler pipe contains a spark arrestor for safety precautions.
• The FP module contains:
  • an electric FP which provides pressurized fuel to the fuel injectors.
  • a fuel level sensor.
  • an inlet filter (sock type).
  • 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 FP module is controlled by the PCM which energizes the FP module relay. Electrical power to the FP module is provided through the IFS switch located in the trunk on the left rear decklid bracket.

The IFS switch is used to de-energize the fuel delivery secondary circuit in the event of a collision. The IFS switch is a safety device that should only be reset after a thorough inspection of the vehicle following a collision.
