Oil Pump 1-Stage 1.4psi w/ hex

The Oil Pump 1-Stage 1.4psi w/ hex from Peterson Fluid is a precision-engineered circulation pump designed for high-performance engine builds and modified vehicles where controlled oil delivery is critical. This single-stage pump provides consistent, reliable oil flow at 1.4 psi, making it suitable for street applications and mild performance enhancements.

Built to Peterson Fluid's OEM-quality standards, this one-stage design delivers steady, non-variable flow without the complexity of dual-stage or variable-displacement units. The hex drive coupling ensures straightforward installation and compatibility with standard oil pump drive systems found in most V8 and inline engine configurations.

Mechanics and engine builders commonly specify Peterson oil pumps for engine rebuilds, stroker builds, and restorations where original equipment has worn or been replaced. At 4.5 lbs and compact 10 x 10 x 12-inch dimensions, this pump integrates seamlessly into tight engine bays without requiring custom fabrication.
