Fuel System

The fuel system consists of:

• a single-speed Mechanical Returnless Fuel System (MRFS) (3.5L vehicles).
• a 2-speed MRFS (2.5L and 3.0L vehicles).
• an All-Wheel Drive (AWD) saddle-type or Front Wheel Drive (FWD) L-shaped fuel tank.
• an Easy Fuel™ (capless) fuel tank filler pipe assembly, which cannot be modified in any way.
• a Fuel Pump (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.
• fuel, vapor and brake tubes in an integrated bundle assembly attached to the underside of the vehicle by retaining clips.
• has a supplemental refueling adapter located in the luggage compartment.
• an Inertia Fuel Shutoff (IFS) switch (3.5L vehicles).
• a FP control module (2.5L and 3.0L vehicles).
• an individual fuel level sensor, AWD vehicles only.
