The Peterson Fluid Systems R4 three-stage oil pump applies a twisted-lobe rotor design with aluminum rotors to cut weight and increase output while keeping size compact. An internal scavenge manifold and shallow screw-in fittings reduce external depth. This left-side, rear-drive drag pump provides 1.4" pressure and 1.4" scavenge, suitable for high-flow race engine oiling requirements.
