Fuel Tank and Lines

Fuel Tank and Lines

The Mechanical Returnless Fuel System (MRFS) consists of the following:

- Fuel tank
- Fuel tank filler pipe, which contains a restrictor plate to permit only an unleaded fuel nozzle to be inserted and a ground strap attached to the frame
- A one-fourth turn fuel tank filler cap
- Fuel filter providing filtration to protect the fuel injectors (located in front of the fuel tank on the LH frame rail)
- Fuel supply and return lines
- A top-mount, bottom-referencing fuel delivery module (located in the fuel tank) containing:
- The electric Fuel Pump (FP) which provides pressurized fuel to the engine
- The fuel level sensor
- An inlet filter
- 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 flow
- A fuel pressure regulator

The FP is controlled by the PCM which energizes the fuel pump relay. Electrical power to the FP is provided through the Inertia Fuel Shutoff (IFS) switch. The IFS switch is located underneath the RH cowl panel.
