Fuel Pump BBC 7.5psi Marine Billet Aluminum

The PRO/CAM Fuel Pump BBC 7.5psi Marine Billet Aluminum (Part #9373) is a mechanical marine fuel pump engineered for Big Block Chevy engines delivering consistent 130 gallons per hour flow. Built from billet aluminum construction, this pump is designed to handle the corrosive salt-air environment and demanding operating conditions encountered on the water, making it a dependable choice for offshore fishing vessels, performance boating applications, and serious freshwater cruisers running large-displacement engines.

Rated at 7.5 psi pressure output, this mechanical pump delivers adequate fuel supply for naturally aspirated Big Block Chevy applications without the complexity of electric pump systems. The 1/2-inch NPT female inlet and outlet ports provide industry-standard marine fuel line compatibility, ensuring straightforward installation into existing engine bay configurations. Weighing only 2.7 pounds with compact dimensions (6 x 5 x 6.6 inches), the unit mounts efficiently in tight engine compartments common to high-performance and retrofit marine builds. Billet aluminum resists corrosion and oxidation far better than cast alternatives, extending service life in saltwater exposure where standard iron pumps deteriorate rapidly.

This pump is ideal for boaters and marine mechanics rebuilding or upgrading Big Block Chevy fuel systems—whether restoring a classic offshore center console, building a weekend tournament fishing rig, or servicing established commercial or recreational vessels. Mechanical fuel pumps eliminate battery drain concerns associated with electric alternatives and operate reliably without electronic control modules or relays, simplifying troubleshooting and reducing electrical system load. The 130 gph output suits naturally aspirated BBC engines across a broad horsepower range, from moderate cruising duty to spirited acceleration scenarios.

Marine fuel systems demand materials that survive constant moisture, salt spray, and temperature cycling. Billet aluminum pumps from PRO/CAM represent a standard upgrade from cast units, providing durability that justifies the investment for serious boaters committed to engine reliability and long service intervals.
