Fuel System - Overview

Overview 

The fuel system consists of:

• Fuel, vapor and brake tubes in an integrated bundle assembly.
• A single container (L-shaped) 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 restrictor plate 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 in the luggage compartment.
• A Fuel Pump Control Module (FPCM).
• A Closed Loop Pressure Control (CLPC) system, which consists of an mechanical returnless fuel system (MRFS) that uses a Low Fuel Pressure Sensor (FPS) mounted directly to the liquid fuel line in addition to a High Fuel Pressure Sensor. The Low Fuel Pressure Sensor provides the Powertrain Control Module (PCM) a fuel pressure reading between the Fuel Pump Module and the High Pressure (HP) Pump. (low side) This allows the PCM to calculate the fuel volume/pressure demand from the Fuel Pump Module more precisely to prevent over-running of the fuel pump. (a fuel economy benefit).
• A Fuel Pump (FP) module containing:
  • The electric FP module which provides pressurized fuel to the high pressure Fuel Pump (FP).
  • The fuel level sensor.
  • 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.

Fuel Pump Shut-off Feature 

In the event of a moderate to severe collision, the vehicle is equipped with a Fuel Pump and Sender Shut-off Feature that is initiated by the event notification signal.
