Fuel System: Notes
The fuel system consists of the:
- saddle-type fuel tank.
- Fuel Pump (FP) module.
- FP control module.
- Easy Fuel ™ (capless) fuel tank filler pipe assembly.
- fuel level sensor assembly.
- fuel level sender (mounted on the FP and the fuel level sensor assembly).
- fuel tubes.
- 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 dual-container (saddle-type) 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 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 in the spare tire compartment.
- 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 RH C-pillar trim panel.
- has fuel tubes (liquid and vapor) along with brake tubes mounted on the underside of the vehicle in a bundle.
- 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.
- has a serviceable fuel level sender mounted on the FP module.
- has a serviceable fuel level sender mounted on the fuel level sensor assembly.
