Pump 3 Stage L/S Std. Vol. 1.2in Body

The Peterson Fluid Pump 3 Stage L/S Standard Volume 1.2in Body (MPN 04-3004) is a three-stage dry sump oil pump engineered for high-performance and racing applications where reliable oil delivery and pressure consistency are non-negotiable. This driver-side universal pump delivers controlled volumetric flow across multiple engine speeds, making it essential for vehicles running extended track sessions, sustained high-RPM operation, or demanding off-road environments where conventional sump systems fail.

The three-stage design allows for progressive oil delivery—initial stages handle lower engine speeds efficiently while the final stage maintains pressure stability as RPM climbs. The 1.2-inch pressure port accommodates standard dry sump system fittings, ensuring compatibility with most aftermarket manifold and tank configurations. Standard volume output balances flow rate against parasitic horsepower loss, a critical consideration in competition builds where every fraction of power matters. At 7.38 lbs, this pump integrates into tight engine bay layouts without requiring extensive structural modification.

This pump is specified for engine builders, fabricators, and racers implementing full dry sump conversions on street rods, circle-track competitors, off-road trucks, and road-race platforms. Dry sump systems eliminate oil starvation during acceleration, braking, and cornering—situations where traditional wet sumps allow oil to slosh away from the pickup. The Peterson 3-stage design pairs well with matching Peterson components in a coordinated system, though the universal mounting allows integration into custom fabrications where pump selection is driven by flow requirements and pressure needs rather than OEM bolt patterns.
