Fuel System
WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The fuel system used on the 6.0L direct injection (DI) turbo diesel engine is controlled by the powertrain control module (PCM).
The fuel system components consist of:
- electric fuel pump.
- high-pressure oil pump.
- fuel filters.
- injection pressure regulator (IPR) valve.
- injection control pressure (ICP) sensor.
- fuel pressure regulator.
- water in fuel switch/fuel heater thermostat.
- fuel injection control module (FICM).
- fuel injectors.
Fuel to be supplied to the combustion chambers passes through the fuel-conditioning module into the secondary fuel filter, then to the cylinder head galleries and then through the electrohydraulic injectors.
Excess fuel not used by the engine bypasses the secondary fuel filter, flows through the fuel pressure regulator assembly and returns to the fuel conditioning module.
