- 220 GPH Pump: Delivers an impressive 220 gallons per hour of fuel, providing the flow needed for high-performance applications.
- 4-Bearing Motor with Intermediate Shaft: Enhances reliability and significantly reduces pump noise for a quieter ride.
- Larger Ports: Features bigger 3/4-16 O-ring boss inlet and outlet ports for improved fuel flow.
- Diaphragm Fuel Pressure Regulator: Allows the pump to be boost-referenced and adjusted from 7-70 PSI for precise control.
- Demand Flow Design: Supplies only the necessary amount of fuel to the engine, improving efficiency and reducing fuel recirculation.
- Reduced Aeration: A 7/16-20 low-flow return prevents air bubbles from forming in the fuel that is sent back to the tank.
- Dual-Feed Motor: Delivers fuel to both sides of the gerotor pump to minimize cavitation and ensure consistent performance.
