The Peterson Fluid Systems R4 three-stage oil pump uses a twisted-lobe rotor design with aluminum rotors to lower mass and increase output in a compact package. An internal scavenge manifold and shallow-depth screw-in fittings create a low profile. This right-side, rear-drive drag pump delivers 1.4" pressure and 1.4" scavenge, offering a high-capacity option for race engine oiling systems.
