Oil Pump Pressure Spring High PSI

The Oil Pump Pressure Spring High PSI by Barnes is a precision-engineered relief spring designed for high-performance oil pump systems. This component is essential for operators and technicians who demand reliable pressure regulation in demanding engine applications. The spring maintains critical pressure thresholds, protecting pump integrity and preventing catastrophic system failure in vehicles subjected to sustained load or extreme operating conditions.

Manufactured from hardened steel with a distinctive yellow finish for easy identification, this high-pressure relief spring is calibrated to manage elevated PSI loads that standard springs cannot withstand. The compact design—measuring 1.7 x 0.55 x 3 inches and weighing just 0.02 lbs—allows for seamless integration into existing Barnes oil pump assemblies. The spring's precise tension characteristics ensure consistent pressure relief across temperature ranges and extended service intervals, preventing pressure spikes that could compromise gaskets, seals, and bearing clearances.

This replacement spring benefits rebuild specialists, engine builders, and fleet maintenance professionals restoring or upgrading high-mileage or performance-oriented engines. Installation requires removal of the pump housing and careful spring replacement to match OEM specifications. The yellow steel construction resists corrosion and fatigue, making it an ideal choice for freshwater marine engines, heavy-duty trucks, and motorsports applications where oil pressure stability directly impacts longevity and performance.
