Fuel Tank and Lines

Fuel Tank and Lines

The fuel system consists of the following components:

- 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
- One-fourth-turn-type fuel tank filler cap on Explorer Sport Trac
- Easy FuelTM capless fuel tank filler pipe on Explorer/Mountaineer
- Fuel filter providing filtration to protect the fuel injectors (located on the front of the fuel tank)
- Fuel tubes
- Vapor tubes
- Fuel Pump (FP) assembly containing:
- the electric FP which provides pressurized fuel to the engine.
- a serviceable fuel level sender.
- an inlet filter.
- a check valve which maintains system pressure after the FP is shut off.

The FP is controlled by the PCM which energizes the FP relay. Electrical power to the FP is provided through the Inertia Fuel Shutoff (IFS) switch.
