Oil Pump 4-Stage 1.4psi Front Pressure

The Oil Pump 4-Stage 1.4psi Front Pressure by PETERSON FLUID is engineered for builders and enthusiasts who demand reliable engine oiling under demanding conditions. This 4-stage pump is designed to provide consistent oil circulation and pressure regulation, making it essential for high-performance applications, custom engine builds, and vehicles running modified fuel systems. Whether you're upgrading a carbureted engine, tuning a classic hot rod, or building a specialized racing engine, this pump ensures your engine receives adequate oil supply and pressure stability across varying RPM ranges.

The 4-stage design delivers multiple pressure stages to optimize oil delivery as engine speed and load increase, preventing oil starvation while maintaining controlled pressure at idle and cruise conditions. The 1.4psi front pressure specification indicates a measured initial relief setting, allowing fine-tuned oil management for engines where stock pressure characteristics don't suit your particular build. The front-mount configuration provides easy installation access and integration into custom oiling systems, while the pump's robust construction handles extended run times and elevated operating temperatures common in performance builds. At 9.1 lbs with compact dimensions of 11 x 11 x 15 inches, this unit balances durability with packaging efficiency in tight engine compartments.

This pump is ideal for engine builders working with custom-carbureted engines, vintage automotive restoration projects, and race-oriented powerplants where OEM pump characteristics are insufficient. Technicians installing dry-sump systems, stroker builds, or high-RPM naturally aspirated engines benefit from the precise pressure regulation this unit provides, ensuring critical engine components—bearings, cam lobes, and rocker assemblies—receive uninterrupted lubrication. Installation requires proper oiling system integration and alignment with your engine's mounting surface; consult your engine's technical specifications to confirm compatibility with your block configuration and oil gallery design.
