The Peterson Fluid Systems R4 three-stage oil pump employs a twisted-lobe rotor design and all-aluminum rotors to reduce weight while boosting output in a compact, modular assembly. Internal scavenge manifolding and shallow screw-in fittings keep the profile slim. This right-side, rear-drive drag model includes front-pressure capability and is built for flexible racing engine mounting.
