Fuel Tank and Lines
WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The fuel system consists of:
- the fuel tank.
- the fuel tank filler pipe which contains a restrictor plate to permit only unleaded fuel to be pumped into the fuel tank.
- a 1/4-turn type fuel tank filler cap.
- a fuel filter providing filtration to protect the fuel injectors.
- fuel lines.
- fuel pressure regulator.
- a fuel pump 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 pressure relief valve for overpressure protection in the event of restricted flow.
The fuel pump is controlled by the powertrain control module (PCM) which energizes the fuel pump driver module. Electrical power to the pump is provided through the inertia fuel shutoff (IFS) switch.
