The Peterson Fluid Systems R4 three-stage oil pump features a twisted-lobe rotor design and aluminum rotors to cut weight while increasing output, packaged as a compact, modular pump. Internal scavenge plumbing and shallow screw-in fittings keep the profile low. This right-side, rear-drive drag configuration provides 1.2" pressure and 1.4" scavenge for drag-specific oiling setups.
