3.5L Gasoline Turbocharged Direct Injection (GTDI)

The fuel system consists of the following:

• Fuel supply tubes
• Fuel vapor tubes
• Fuel Pump (FP) module (located in the fuel tank)
• High pressure Fuel Pump (FP) (located in the left valve cover)
• Lifetime fuel filter (serviced as part of the FP module)
• Fuel tank filler pipe assembly
• Fuel tank
• Fuel rail
• Fuel injectors
• Fresh air tube (located on top of the transmission)
• Easy Fuel™ (capless) fuel tank filler pipe assembly (which cannot be modified in any way)
• Supplement refueling adapter (located with the vehicle jack)
• Two-speed Mechanical Returnless Fuel System (MRFS)

The vehicle is equipped with a Gasoline Turbocharged Direct Injection (GTDI) system.

Fuel delivery is accomplished through a MRFS.

• The FP module supplies pressurized fuel to the high pressure FP.
• The high pressure FP supplies high pressure low volume fuel pressure to the fuel rails.
• The fuel injectors are separately controlled and mounted to the intake manifold for each cylinder.
• The fuel tubes route the fuel from the FP to the fuel rail.
• The fuel filter cleans the fuel delivered from the FP to the fuel rail.
