Fuel pump module


The fuel pump module is used on all vehicles except vehicles with diesel engines.

Fuel through the fuel manifold, which is equipped with a fuel pressure regulator, is supplied at high pressure to the fuel injectors.

Fuel level sensor


The fuel level sensor is only used on vehicles with a diesel engine.

Vehicles with 75 hp diesel engine or 90 hp


Fuel is drawn from the fuel tank by the high pressure fuel pump, which then delivers high pressure fuel to the fuel injectors.

Common Rail Fuel Injection Vehicles


Fuel is drawn from the fuel tank by the high pressure fuel pump, which then delivers high pressure fuel to the fuel manifold, which then delivers fuel to the fuel injectors.


Vehicles with 2.0L Duratec ST engine


The vehicle is equipped with an electronically controlled non-returnable fuel system. The benefits of a non-return fuel system are improved fuel vapor control, lower fuel temperature, and less fuel vapor in the fuel tank. The fuel pressure sensor installed in the fuel rail sends a signal to the common electronic module (GEM). Using this pressure information, the GEM regulates the voltage applied to the fuel pump module, which in turn changes the fuel flow provided by the pump.

Fuel composition adjustment module - vehicles with fuel composition adjustment


The fuel pump module wiring on vehicles with fuel composition trim is equipped with a fuel composition trim module that converts DC voltage to AC voltage. Conversion is necessary to prevent galvanization «cards» fuel sensor built into the fuel pump module when ethanol based fuel is used.

All cars


The IFS switch cuts off power to the fuel pump in the event of a collision.

Fuel lines (fuel lines) made of metal, but have flexible connections.

The fuel lines are supplied as a kit and clipped to the brake lines.

The fuel line ground clamp is the only grounding path for dissipating static electricity from the fuel lines. If the clamp is missing or broken, a new matching Ford clamp should be installed.
