The Oil Pump 3-Stage 1.4psi Left Side from Peterson Fluid is a precision-engineered component designed for engine builders and performance enthusiasts who demand reliable oil circulation in high-output or modified engines. This three-stage pump is engineered to maintain consistent oil delivery at 1.4 PSI, ensuring proper lubrication flow under demanding conditions where traditional single-stage pumps fall short. Whether you're building a competition engine, restoring a classic with upgraded performance specs, or assembling a street machine with increased RPM capability, this left-side-mounted configuration delivers the dependable pressure management your build requires.
The three-stage design of this Peterson Fluid oil pump provides progressive oil delivery that adapts to varying engine loads and speeds, making it ideal for applications where pressure consistency matters more than peak output. Each stage operates independently, allowing the pump to optimize flow delivery across idle, cruise, and wide-open-throttle conditions without excess pressure spikes that can compromise gasket integrity or oil line fittings. The left-side mounting configuration accommodates specific block layouts common in drag racing, street rod, and vintage muscle car platforms, while the compact 8 x 11 x 15-inch footprint integrates cleanly into tight engine bay setups. At 7.5 pounds, the unit is lightweight enough for performance applications where unsprung weight reduction matters, yet robust enough to handle continuous operation at elevated RPMs.
This pump is ideal for engine builders, performance shops, and dedicated hobbyists working on custom or modified engines where OEM pump capacity or pressure profile proves inadequate. Installation requires proper plumbing integration, suction pickup configuration, and pressure relief calibration to match your specific engine displacement and target RPM range. Verify left-side mounting compatibility with your block configuration and ensure that existing oil gallery ports align with your chosen installation approach. Pair this pump with a high-quality oil filter, appropriate viscosity lubricant for your engine type, and properly routed supply lines to maximize longevity and protection across your entire drivetrain.
