Fuel System: Notes
The fuel system consists of the:
- L-shaped fuel tank.
- Fuel Pump (FP) module.
- FP control module.
- Easy Fuel™ (capless) fuel tank filler pipe assembly.
- Inertia Fuel Shutoff (IFS) switch.
- fuel tubes (liquid and vapor).
- fuel injectors.
- fuel rail.
- Fuel Tank Pressure (FTP) sensor (part of the fuel vapor tube assembly).
The vehicle:
- uses a 2-speed Mechanical Returnless Fuel System (MRFS).
- uses a standard (L-shaped) fuel tank.
- has a FP module that supplies fuel under pressure to the fuel rail.
- has a lifetime fuel filter (serviced as part of the FP module).
- has a serviceable fuel level sender mounted on the FP module.
- has an Easy Fuel™ (capless) fuel tank filler pipe assembly, which cannot be modified in any way and is serviced only by the installation of a new fuel tank filler pipe assembly.
- has a supplemental refueling adapter, located behind RR quarter trim access panel.
- has a FP module that operates on 10 or 12 volts depending on load, that supplies fuel under pressure to the fuel rail.
- has a FP control module located behind the fuel tank, mounted to the underside of the vehicle.
- has an IFS switch located behind the RH cowl trim panel.
- has fuel tubes (liquid and vapor) along with brake tubes mounted on the underside of the vehicle in a bundle.
- has a FTP sensor (part of the fuel vapor tube assembly).
- is equipped with a sequential Multi-Port Fuel Injection (MFI) system.
- uses separately controlled fuel injectors for each cylinder. The fuel injectors are mounted to the intake manifold.
- fuel injectors are supplied with pressurized fuel from the FP module to the fuel rail.
- fuel injection rail pressure is controlled by the electronic FP module which is enabled by the PCM.
