Fuel System - General Information - Gasoline and Diesel

Fuel System - Gasoline Engines

The gasoline fuel system consists of the following:

- Fuel and vapor tubes
- Fuel filter (located on the LH frame rail)
- Fuel Pump (FP) module (located in the fuel tank)
- Fuel tank filler pipe assembly
- Fuel tank
- Inertia Fuel Shutoff (IFS) switch (located on the RH side of the instrument panel)

The vehicle is equipped with electronic Multi-Port Fuel Injection (MFI) that is supplied by an Electronic Returnless Fuel System (ERFS). The PCM receives pressure information from a fuel pressure sensor mounted on the fuel rail. The PCM is able to maintain constant fuel pressure by varying the FP module output. This is accomplished by increasing or decreasing voltage supplied to the FP module. The returnless fuel system offers improved economy, lower fuel temperatures and decreased fuel vapor in the fuel tank.
