The Peterson R4 6-stage oil pump is a right-side mount, rear-drive assembly offering 1.4" pressure and 1.4" scavenge capacity. It uses the companys twisted lobe rotor architecture to enable lightweight all-aluminum rotors and higher output. The pump's internal scavenge manifold and shallow-depth screw-in fittings produce a low-profile, modular unit that can be configured for front or rear drive mounting in racing engine installations.
