Fuel System
WARNING:
Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited, resulting in possible personal injury.
The fuel system consists of:
- an electronic returnless fuel system.
- the standard fuel tank.
- a fuel tank filler pipe assembly which cannot be modified in any way and is serviced only by replacement with a new filler pipe assembly.
- a high temperature composite shield on the right side of the fuel tank to protect the fuel tank from the exhaust system.
- a fuel tank filler pipe which contains a restrictor plate to permit only unleaded fuel to be pumped into the fuel tank.
- a 1/4 turn fuel tank filler cap.
- a fuel filter providing filtration to protect the fuel injectors.
- fuel lines.
- fuel pressure sensor.
- a top mount, bottom sense fuel delivery module containing:
- the electric fuel pump which provides pressurized fuel to the engine on demand.
- the fuel level sensor.
- 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 air flow.
The fuel pump is controlled by powertrain control module (PCM). Electrical power to the pump is provided through the inertia fuel shutoff switch (IFS switch) located in the jack access panel on the RH side interior rear quarter trim panel.
