FUEL TANK AND LINES

WARNING:
- Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious 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 component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
- When handling fuel, always observe fuel handling precautions and be prepared in the event of fuel spillage. Spilled fuel may be ignited by hot vehicle components or other ignition sources. Failure to follow these instructions may result in serious personal injury.
- Remove the fuel filler cap slowly. The fuel system may be under pressure. If the fuel filler cap is venting vapor or if you hear a hissing sound, wait until it stops before completely removing the fuel filler cap. Otherwise, fuel may spray out. Failure to follow these instructions may result in serious personal injury.
- Do not use an open flame to shrink the heat shrink tube. Use a heat gun only. Fuel residue may be ignited if an open flame is used. Failure to follow this instruction may result in serious personal injury.
- Before working on or disconnecting any of the fuel tubes or fuel system components, relieve the fuel system pressure to prevent accidental spraying of fuel. Fuel in the fuel system remains under high pressure, even when the engine is not running. Failure to follow this instruction may result in serious personal injury.

The fuel tank and lines consists of the:
- fuel tank.
- fuel tank filler pipe.
- fuel tank filler cap.
- fuel pump (FP) module.
- fuel level sensor.
- fuel tubes.
- fuel tank pressure (FTP) sensor.
- inertia fuel shutoff (IFS) switch.

The vehicle:
- utilizes an electronic returnless fuel system.
- has a dual-container (saddle type) stamped steel fuel tank, each half equipped with a fuel level sensor.
- has a FP module that supplies fuel under pressure to the fuel rail.
- has a fuel tank filler pipe which contains a restrictor plate to permit only unleaded fuel to be pumped into the fuel tank.
- has a fuel tank filler pipe assembly that cannot be modified in any way. The fuel tank filler pipe is serviced only by installing a new filler pipe assembly.
- has a 1/4 turn fuel tank filler cap.
- has an electronic returnless fuel system.
- has a fuel filter that is mounted in front of the fuel tank on the left hand side of the vehicle providing filtration to protect the fuel injectors.
- has fuel tubes (liquid and vapor) combined in a bundle along with the brake tubes mounted on the underside of the floorpan and covered with a protective cover shield.
- has a FTP sensor (part of the fuel vapor tube assembly).
- has quick connect and spring lock fuel tube couplings.

The FP module is controlled by the PCM. Electrical power to the FP is provided through the IFS switch located in the passenger footwell area.
