Fuel Selector Valve: Description

Systems usually consist of a fuel selector switch, fuel pump relay (some models), tank selector valve, inertia switch (some models) and fuel pump. Tank selector valves may contain a different amount of ports depending upon application. See Figure .

Some Ford Motor Co. models with Electronic Fuel Injection (EFI) may contain a dual function reservoir in place of the 6-port valve. See Figure . This alters fuel delivery by fuel pressure placed on a diaphragm. The reservoir is not electrically controlled.

Some Ford Motor Co 7.5L models may contain a Hot Fuel Handling system. This system uses 2 electric fuel pumps in the fuel tank and fuel pump cut-off relay. On 7.5L models without Hot Fuel Handling, electric fuel pumps and cut-off relay are not used. See Figure and Figure . These systems contain different components and test procedures.
