Oil Pump Single Stage Rev Rotation w/FP Drive

The Oil Pump Single Stage Rev Rotation w/FP Drive is a critical component for engine builders and performance enthusiasts looking to optimize oil delivery in reverse-rotation applications. This specialized pump is engineered for engines that require counter-clockwise rotation—common in front-engine, rear-wheel-drive vehicles with certain belt configurations or in retrofit scenarios where standard clockwise pumps won't fit the intended setup. Whether you're building a street machine, race engine, or restoring a classic with modified architecture, this reverse-rotation pump ensures consistent oil pressure and flow to vital engine components.

Manufactured by MOROSO, a trusted name in high-performance engine accessories, this single-stage pump features an FP (fuel pump) drive interface, allowing direct mounting and indexing to compatible fuel pump eccentric drives or accessory drive systems. The single-stage design delivers steady, reliable oil pressure without the surge characteristics of gear-driven alternatives, making it ideal for street and competition engines alike. The compact footprint—measuring 7.7 x 7.3 x 8.6 inches and weighing just 5.95 lbs—integrates cleanly into tight engine bay layouts while maintaining the structural rigidity demanded by high-RPM operation and sustained pressure loads.

This pump is essential for builders working with non-standard crankshaft or accessory drive orientations, particularly in custom street rods, engine transplants, and performance rebuilds where conventional oil pump options simply won't work. Installation requires verification of rotational direction relative to your drive source and confirmation of pressure specifications for your engine displacement and bearing clearances. Proper sizing and installation ensure that all galleries, lifters, rocker arms, and bearing surfaces receive uninterrupted lubrication, directly impacting engine longevity and reliability even under sustained boost, high load, or extended track use.
