Oil Pump 1-Stage 1.4psi Reverse Rotation

The Oil Pump 1-Stage 1.4psi Reverse Rotation by Peterson Fluid is a high-volume, high-pressure oil circulation system engineered for custom and performance engine builds requiring precision lubrication control. Designed for wet sump applications, this reverse-rotation pump delivers consistent oil flow and pressure regulation in engines where standard pump rotation won't fit tight engine bay configurations. Built for builders and enthusiasts who demand reliable, dependable oil delivery under demanding conditions, this pump solves installation challenges while maintaining the flow and pressure characteristics critical to engine longevity.

This single-stage pump features a 3/8-inch hex drive interface, allowing flexible coupling to various drive systems common in custom engine builds. The aluminum construction keeps weight minimal while maintaining strength and durability, and the 1.4 psi pressure rating delivers high-volume flow suitable for complex oiling circuits in race engines and hot rods. Reverse rotation capability makes this pump ideal for engine configurations where clockwise drive is impractical, such as rear-mounted distributors or dual-belt systems. The pump's R4 wet sump design ensures consistent suction and priming in varied mounting orientations.

Performance engine builders, hot rod fabricators, and race teams benefit most from this pump's reverse-rotation capability and high-volume output. Installation works best when paired with compatible drive systems—belt drives, gear drives, or shaft-coupled arrangements—that allow the 3/8-inch hex to be engaged reliably. Verify your engine's oiling circuit design and drive direction before purchase to ensure this reverse-rotation configuration matches your build requirements. With Peterson Fluid's reputation for precision engineering, this pump integrates seamlessly into purpose-built oiling systems where standard pumps cannot function.
