Fuel Tank and Lines

Fuel Tank and Lines

The fuel tank and lines consists of the:

- saddle-type fuel tank or a L-shaped fuel tank.
- fuel tank filler pipe.
- fuel tank filler cap.
- Fuel Pump (FP) module.
- fuel level sensor assembly (saddle-tank only).
- fuel level sender (mounted on FP and, if equipped, the fuel level sensor assembly).
- fuel tubes.
- Fuel Tank Pressure (FTP) sensor.
- Inertia Fuel Shutoff (IFS) switch.

The vehicle:

- uses a Mechanical Returnless Fuel System (MRFS).
- uses either a single container (L-shaped) or a dual-container (saddle-type) fuel tank.
- has a fuel level sensor assembly (saddle-tank only).
- has a FP module that supplies fuel under pressure to the fuel rail.
- has a fuel filter (part of the FP module).
- has fuel tubes (liquid and vapor) along with brake tubes mounted on the underside of the vehicle in a bundle.
- has a FTP sensor (part of the fuel vapor tube assembly).
- 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 and is serviced only by installation of a new fuel tank filler pipe assembly.
- has an IFS switch located in the passenger side footwell that shuts off fuel in the event of a collision.
- has a fuel level vent valve (part of the FP module on Taurus X federal emission vehicles, part of the fuel tank on all other vehicles).
- has a serviceable fuel level sender mounted on the FP module.
- has a serviceable fuel level sender mounted on the fuel level sensor assembly (saddle-tank only).

The FP is controlled by the PCM. Electrical power to the FP is provided through the IFS switch.
