The Peterson Fluid Systems R4 three-stage oil pump uses a twisted-lobe rotor layout with all-aluminum rotors to cut weight while boosting output, packaged as a low-profile modular unit. An internal scavenge manifold and shallow screw-in fittings keep clearances minimal. This right-side mount, rear-drive version is built for racing engine installations where flexible drive orientation is required.
