Oil Pump Pressure Spring Low PSI

The Oil Pump Pressure Spring Low PSI from Barnes is an essential replacement component for engine lubrication systems that require precise oil pressure regulation. This low-pressure variant is specifically designed for applications needing reduced spring tension, making it suitable for modified engines and pump rebuilds. It is particularly beneficial for those addressing chronic low-oil-pressure issues.

This spring functions as a mechanical governor, controlling the bypass valve operation to maintain target oil pressure across varying engine speeds and load conditions. The low-PSI calibration allows oil to reach designated pressure thresholds at lower engine RPMs, which is crucial for performance builds. Weighing just 0.02 lbs, it is engineered to fit OEM dimensions of 2.7 x 0.7 x 2.9 inches.

Engine builders, experienced DIY mechanics, and technicians servicing high-mileage or modified powerplants will find this verified replacement spring invaluable. Installation requires oil pump removal and disassembly, ensuring that the spring can be integrated into existing pump assemblies effectively. Having this component on hand can help maintain consistent oil flow during critical engine operations.
