Fuel Tank and Lines
FUEL TANK AND LINESWARNING:
- 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.
- Do not carry personal electronic devices such as cell phones, pagers or audio equipment of any type when working on or near any fuel-related components. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions can result in personal injury.
The fuel system consists of:
- a stamped steel fuel tank.
- fuel tubes (liquid and vapor) combined in a bundle along with brake tubes mounted on the underside of the floorpan by retainer clips.
- quick connect fuel tube couplings.
- a fuel tank filler pipe assembly, which cannot be modified in any way, that also contains a restrictor plate to permit only unleaded fuel to be pumped into the tank.
- a 1/4 turn-type fuel tank filler cap.
- an inertia fuel shutoff (IFS) switch.
- a mechanical returnless fuel system.
- a fuel pump module (FPM) containing:
- the electric fuel pump which provides pressurized fuel to the engine.
- the fuel level sensor.
- a check valve which maintains system pressure after the pump is shut off.
- a pressure relief for overpressure protection in the event of restricted airflow.
- a fuel filter providing filtration to protect the fuel injectors from foreign material.
The fuel pump is controlled by the powertrain control module (PCM). Electrical power to the pump is provided through the inertia fuel shutoff (IFS) switch located under the right front kick panel.
