1/4in. Ford Oil Pump Primer

The 1/4in. Ford Oil Pump Primer from Moroso is an essential tool for engine builders and mechanics performing initial startup procedures on freshly rebuilt or newly assembled Ford engines. This specialized primer eliminates the critical risk of running an engine with inadequate oil pressure during first ignition, which can lead to catastrophic bearing damage or complete engine failure within seconds. It is particularly beneficial for those breaking in modified stroker motors, installing performance crate engines, or commissioning complete engine rebuilds.

This primer ensures that oil circulates through all galleries and bearing surfaces before combustion begins. The 1/4 inch connection port integrates seamlessly with standard Ford oil system fittings and allows direct mechanical drive from the engine's block or crankshaft, depending on the application and installation setup. By priming the oil pump before engine start, this tool pressurizes the entire lubrication system, guaranteeing that a protective oil film exists at every critical friction point the moment the engine fires.

Street enthusiasts, drag racers, and full-restoration builders will find this primer indispensable for ensuring engine longevity and performance reliability. It is compatible with various Ford engines, including the 289, 302, 351W, 427, and 460 models. The compact and durable construction weighs just 0.38 lbs, making it easy to handle during the setup phase while delivering reliable, repeatable priming action across multiple engine builds.
