Melling M-83HV oil pump for the 1977-1996 Ford F-150 V8 5.8L and other vehicles is a high volume gear pump that supplies additional oil to the engine. This Melling high volume oil pump is a stock-replacement unit with standard pressure, and it comes with its gasket.
A worn engine oil pump can show up as a low oil pressure reading, an oil pressure warning light or weak pressure at idle. Before you replace the pump, rule out a low oil level, a faulty oil pressure sender or gauge and a blocked pickup screen, since each can give similar readings; a shop can test the actual oil pressure.
This Melling oil pump is a gear pump for the 1977-1996 Ford F-250 V8 5.8L, the 1969-1973 Ford Mustang V8 5.8L and many other Ford, Lincoln and Mercury models, with one pump per engine. Owners of other models can find their car in the “Vehicles it fits” section.
