Fuel System

The fuel system consists of the:

• All-Wheel Drive (AWD) saddle-type or Front Wheel Drive (FWD) L-shaped fuel tank.
• Fuel Pump (FP) module.
• fuel level sensor assembly (saddle-type fuel tank).
• fuel level sender (mounted on the FP module and, if equipped, on the fuel level sensor assembly).
• Easy Fuel™ (capless) fuel tank filler pipe assembly.
• FP control module on 2.5L and 3.0L vehicles.
• Inertia Fuel Shutoff (IFS) switch on 3.5L vehicles.
• fuel tubes.
• fuel injectors.
• fuel rail.
• Fuel Tank Pressure (FTP) sensor (part of the fuel vapor tube assembly).

The vehicle

• has a single speed Mechanical Returnless Fuel System (MRFS) on 3.5L vehicles.
• has a 2-speed MRFS on 2.5L and 3.0L vehicles.
• has either a single container (L-shaped) (FWD) or a dual container (saddle-type) (AWD) fuel tank.
• has a FP module containing:
  • an electric FP, which provides pressurized fuel to the fuel rail.
  • a serviceable fuel level sender.
  • a check valve, which maintains system pressure after the FP is shut off.
  • a pressure relief valve for overpressure protection in the event of restricted fuel flow.
  • a lifetime fuel filter providing filtration to protect the fuel injectors from foreign material.
• has an individual fuel level sensor, AWD vehicles only.
• has a fuel rail-mounted Schrader valve on early build 3.0L vehicles.
• has fuel, vapor and brake tubes in an integrated bundle assembly attached to the underside of the vehicle by retaining clips.
• has an Easy Fuel™ (capless) fuel tank filler pipe assembly, which cannot be modified in any way.
• has a supplemental refueling adapter located in the luggage compartment.
• 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.
