Delphi Mechanical Fuel Pump P/N:MF0121
Delphi MF0125 mechanical fuel pump for the 1979 Ford Mustang V8 5.0L, the 1980-1982 Mustang V8 4.2L and other vehicles moves fuel from the tank toward the engine. This Delphi mechanical fuel pump is built to its own OE standards.
Hard starting, stalling under load or fuel wetness around the pump body can mean the pump is wearing out. A clogged fuel filter, a restricted fuel line or a weak ignition can produce similar symptoms, so find the cause before you buy a pump.
Besides the Mustang, the vehicles it fits include the 1980 Ford Thunderbird V8 4.2L, the 1980-1981 Thunderbird V8 5.0L, the 1982 Thunderbird V8 4.2L, the 1980 Mercury Cougar V8 4.2L, the 1980-1981 Cougar V8 5.0L and the 1982 Cougar V8 4.2L.
