Fuel System - Overview: Notes

The fuel system consists of: 

• a Closed Loop Pressure Control (CLPC) system.
• fuel and vapor lines in an integrated bundle assembly.
• a single container fuel tank.
• quick connect fuel and vapor tube couplings.
• a fuel tank filler pipe assembly, which cannot be modified in any way, that also contains a misfuel inhibitor device to permit only unleaded fuel to be pumped into the tank.
• 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.
• a supplemental refueling adapter located behind the rear seat.
• a Fuel Pump Control Module (FPCM) located on the frame rail above the rear of the Fuel Tank.
  • a Fuel Pump (FP) module containing: 

• the electric FP module which provides pressurized fuel to the high pressure Fuel Pump (FP).
• the fuel level sender.
• a check valve which maintains system pressure after the pump is shut off.
• a pressure relief for overpressure protection in the event of restricted fluid flow.
• a lifetime fuel filter providing filtration to protect the fuel injectors from foreign material.
