WARNING: This page is about a different car, the 2009 Mercury Grand Marquis and 2009 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
The fuel system consists of the:
- fuel filter.
- fuel injectors.
- Fuel Pump (FP) module.
- fuel rail.
- fuel rail pressure and temperature sensor.
- fuel tank.
- fuel tank filler cap.
- fuel tank filler pipe.
- Fuel Tank Pressure (FTP) sensor.
- fuel tubes (liquid and vapor).
- Inertia Fuel Shutoff (IFS) switch.
The vehicle:
- is equipped with a sequential Multi-Port Fuel Injection (MFI) system.
- uses separately controlled fuel injectors mounted to the intake manifold for each cylinder.
- has a FP module that supplies fuel under pressure to the fuel rail.
- has fuel tubes (liquid and vapor) mounted on the underside of the vehicle in a bundle.
- has a FTP sensor (part of the fuel vapor tube assembly).
- uses separately controlled fuel injectors for each cylinder. The fuel injectors are mounted to the intake manifold.
- fuel injectors are supplied with pressurized fuel from the FP module to the fuel rail.
- has a fuel rail which is equipped with a fuel rail pressure and temperature sensor.
- fuel injection rail pressure is controlled by the electronic FP module which is enabled by the PCM.
- has a one-fourth turn vented type fuel tank filler cap.
- has a fuel tank filler pipe assembly, which cannot be modified in any way, that also contains a restrictor plate to permit only unleaded fuel to be pumped into the fuel tank.
- has a fuel tank filler pipe check valve that prevents spitback during refueling.
- has an IFS switch located in the passenger side footwell that shuts off fuel in the event of a collision.
