• is a 2-speed Mechanical Returnless Fuel System (MRFS) with sequential Multi-Port Fuel Injection (MFI).
• uses a dual-container (saddle-type) fuel tank.
• has a fuel level sensor assembly.
• has a Fuel Pump (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 upper quarter 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).
• uses separately controlled fuel injectors for each cylinder. The fuel injectors are mounted to the intake manifold and are supplied with pressurized fuel from the FP module to the fuel rail.
• fuel 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.
