Fuel Tank and Lines
WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The fuel system consists of the following:
- Fuel tank
- Fuel tank filler pipe which contains a restrictor plate to permit only unleaded fuel to be pumped into the fuel tank
- Electronic returnless fuel system
- 1/4 turn-type fuel tank filler cap
- Fuel filter providing filtration to protect the fuel injectors
- Fuel line
- Fuel pump assembly containing:
- the electric fuel pump which provides pressurized fuel to the engine.
- the fuel level sensor.
- an inlet filter.
- a check valve which maintains system pressure after the pump is shut off.
- a fuel pump driver module
The fuel pump is controlled by the powertrain control module (PCM) which energizes the fuel pump relay. Electrical power to the pump is provided through the inertia fuel shutoff (IFS) switch.
