Fuel Tank And Lines
WARNING:
- Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions can result in personal injury.
The mechanical returnless fuel system (MRFS) consists of:
- The fuel tank
- The fuel tank filler pipe which contains a restrictor plate to permit only an unleaded fuel nozzle to be inserted
- A 1/8 turn fuel tank filler cap
- A fuel filter providing filtration to protect the fuel injectors
- Fuel supply line
- A top-mount, bottom-sense fuel delivery module containing:
- The electric fuel pump which provides pressurized fuel to the engine
- The fuel level sensor
- An inlet filter
- A check valve which maintains system pressure after the pump is shut off
- A pressure relief valve for overpressure protection in the event of restricted flow
- A fuel pressure regulator
The fuel pump is controlled by the powertrain control module (PCM) which energizes the fuel pump relay. Electrical power to the pump is provided through the fuel shutoff switch. The fuel shutoff switch is located on the toe board to the left of the right-hand kick panel.
