Ext Oil Pump 3-Stage Tri-Lobe LHS FP Drive

The Ext Oil Pump 3-Stage Tri-Lobe LHS FP Drive by MOROSO is a heavy-duty external oil pump designed for high-performance and racing applications where factory internal pump capacity falls short. This left-hand suction (LHS) configuration is essential for builders running dry-sump systems, extreme horsepower builds, or engine platforms requiring independent oil circulation control. Whether you're building a competition engine, retrofitting a classic muscle car, or upgrading a street performance platform, this external pump delivers consistent flow and pressure when stock systems cannot keep pace with demand.

The three-stage tri-lobe rotor design maximizes volumetric efficiency and provides smooth, continuous flow across the entire RPM range without pulsation spikes that stress internal passages. MOROSO engineered this pump with FP (fuel pump style) drive compatibility, allowing flexible mounting and power-take-off options from belt, shaft, or accessory drive systems common in race-prepped engines. The tri-lobe configuration generates superior displacement compared to traditional gear pumps while operating at lower speeds, reducing heat generation and extending component life during sustained high-RPM operation.

Cast iron construction ensures durability and thermal stability under demanding conditions where aluminum alternatives may fail. This pump is ideal for circle-track racers, drag racing teams, and serious street performance enthusiasts who require precise oil management. With a weight of 8.5 lbs, it is designed to meet the rigorous demands of high-performance applications.
