The Peterson R4 two-stage oil pump uses twisted-lobe rotors and aluminum rotor construction to deliver both pressure and scavenge capacity in a compact, modular package. This left-side mount two-stage unit provides 1.2" pressure and 1.2" scavenge per the specification, includes a rear-drive provision for accessories, and keeps a low profile with shallow screw-in fittings for easier installation in tight applications.
