Oil Pump 5 Stage R/S w/ Drive

The Peterson Fluid 04-5076 is an R4 5-stage dry sump oil pump designed for right-side mounting. It features one high-volume pressure stage and four high-volume scavenge stages. Engineered for motorsports, it uses a twisted lobe rotor design for consistent oil pressure with high-temperature, low-viscosity oils, and powerful vacuum to reduce crankcase windage. It is constructed from lightweight 6061 T6 aluminum housings and rotors, with a 5/8" steel drive shaft (3/16" keyway). Includes a rear drive provision for accessories (fuel, vacuum, power steering pumps) with separate adapters. Oil pressure is adjustable with a built-in relief. Made in the USA.
