Peterson Fluid Systems pfs04-5094

The Peterson R4 five-stage oil pump in right-side mount with rear drive and reserve rotation uses twisted-lobe rotors and aluminum components to reduce weight while preserving oil pressure and scavenging ability. Its shallow fittings and modular, low-profile design make it adaptable to race engines where space is limited and reliable scavenge vacuum is required to reduce windage.
