Fuel System - Gasoline Engines
WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The gasoline fuel system consist of:
- fuel and vapor tubes.
- fuel filter.
- fuel pump (FP) module.
- fuel tank filler pipe assembly.
- fuel tank.
- inertia fuel shutoff (IFS) switch.
The vehicle is equipped with electronic multiport fuel injection that is supplied by an electronic returnless fuel system. 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.
