Oil Pump 4 Stage R/S w/ Rear Drive Drag

The Peterson Fluid Oil Pump 4 Stage R/S with Rear Drive Drag (MPN 04-4074) is a professional-grade dry sump oil pump engineered for high-performance racing and custom engine builds. This external 4-stage pump delivers standard volume output and mounts on the right side of the engine, making it ideal for applications where traditional wet-sump oiling cannot meet performance demands or packaging constraints.

The 4-stage design provides multi-stage scavenging and pressure capabilities, essential for maintaining oil return from the pan during sustained high-G acceleration, cornering, and inverted maneuvers common in drag racing and road racing. The rear drive drag configuration indicates the pump is optimized for vehicles with rear-mounted drivetrains or custom mounting applications where space and orientation require non-standard pump geometry. Peterson's external pump design allows full system customization and independent tuning of pressure and scavenging stages—a critical advantage over factory integrated systems.

This pump is suitable for serious competitors and engine builders who demand precise oiling control in extreme racing environments. Dry sump systems are standard in professional drag racing, circuit racing, and off-road competition where oil starvation during acceleration, braking, or sustained cornering would damage engine bearings. The universal mounting design accommodates various engine platforms and custom installations, though proper belt drive sizing and system integration are essential for safe operation.

Weighing 8.95 lbs, this pump is compatible with external dry sump tank and filtration systems. Installation requires professional-level mechanical knowledge and proper belt tensioning, bearing support, and return line sizing to function correctly.
