Fuel Tank and Lines
WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. 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
- Fuel tank filler pipe which contains a spark arrestor for safety precautions
- A 1/4 turn type fuel tank filler cap
- A new design fuel filter providing filtration to protect the fuel injectors
- Fuel tubes
- A fuel pump module containing:
- the electric fuel pump which provides pressurized fuel to the engine.
- the fuel level sensor.
- an inlet filter (sock type).
- 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 relay. Electrical power to the pump is provided through the inertia fuel shutoff switch (IFS switch) located in the trunk on the left rear decklid bracket.
