Key Features

This Pro Series fuel pump features a billet 6061-T6 aluminum manifold that eliminates porosity concerns common with cast aluminum units. The contoured CNC-machined passages optimize flow, reducing pressure drops caused by flow restrictions and ensuring consistent fuel delivery. Its universal carbon steel mounting bracket is heavy-duty and easily mounts with supplied hardware, simplifying installation. The "marine grade" motor is protected against dust intrusion and powerful water jets, providing reliable operation in tough environments. Helical bronze spur gears are used for their forgiving nature when contaminants are present, contributing to the longevity and smooth operation of the pump. Overall, this fuel pump combines advanced materials and engineering to deliver dependable performance and durability.

Construction & Design

The use of billet 6061-T6 aluminum for the manifold ensures high strength and resistance to porosity, addressing common cast aluminum issues. CNC machining of the manifold passages guarantees precise flow paths that support optimal fuel flow and pressure stability. The heavy-duty carbon steel mounting bracket provides a secure and stable installation, while the marine-grade motor is designed to withstand harsh conditions, including dust and water exposure. The helical bronze spur gears are engineered for durability and smooth operation, even in contaminated fuel environments.
