Gasoline Engines
WARNING: This page is about a different car, the 2010 Ford Pickup, 2010 Ford F550 Super Duty, 2010 Ford F450 Super Duty, and 2010 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The gasoline fuel system contains:
- a fuel tank. There are 3 available:
- a midship fuel tank (mounted to the LH frame side rail).
- an auxiliary fuel tank (mounted to the LH frame side rail).
- an aft-of-axle fuel tank (mounted between the side rails).
- a fuel tank filler pipe which contains a restrictor plate to permit only unleaded fuel to be pumped into the fuel tank.
- a one-fourth turn fuel tank filler cap.
- a fuel filter providing filtration to protect the fuel injectors.
- fuel and vapor tubes.
- a fuel rail-mounted fuel pressure and temperature sensor.
- a Fuel Pump (FP) which provides pressurized fuel to the engine and has:
- a serviceable fuel sender.
- an inlet filter.
- a check valve which maintains system pressure after the FP is shut off.
- a pressure relief valve for overpressure protection in the event of restricted flow.
- an Inertia Fuel Shutoff (IFS) switch
- a Fuel Pump Driver Module (FPDM)
The fuel tank stores the liquid fuel. Electrical power to the FP is provided through the IFS switch. The fuel pump module is controlled by the PCM through the FPDM . The fuel pump provides fuel to the fuel rail through the fuel supply tube. Vapor tubes route fuel vapor to the Evaporative Emission (EVAP) canister and the intake manifold through the EVAP canister purge valve.
