Fuel Pump SBC 7.0-8.5 -8 AN Inlet -8AN Outlet

The ALLSTAR PERFORMANCE Fuel Pump SBC 7.0-8.5 -8 AN Inlet -8AN Outlet is a mechanical fuel pump engineered for small block Chevy engines requiring a reliable, direct-feed fuel delivery system. This aluminum pump delivers 172 gallons per hour at 7.0–8.5 psi, providing adequate pressure and volume for carburetor-fed street engines, race applications, and restored classics.

The pump features -8 AN male inlet and outlet ports, enabling seamless integration into fuel systems using modern braided hose and AN fittings—a standard in hot rod and performance builds. The 7.0–8.5 psi pressure range is optimized for mechanical operation from a camshaft-driven eccentric, avoiding over-pressurization that can damage traditional carburetors and float bowls. Aluminum construction reduces weight while maintaining the durability required for engine compartment mounting. As a mechanical pump, it operates independently of electrical power, making it a dependable choice for vehicles with minimalist ignition systems, vintage restorations, or off-grid applications.

This pump is purpose-built for SBC small block Chevy engine platforms, including 350, 383, and 427 variants commonly found in street rods, race cars, and vintage truck restorations. Builders choosing mechanical fuel delivery over electric systems value simplicity, reliability in high-heat engine bays, and the traditional aesthetic of vintage fuel system components. The 172 gph output supports engines in the naturally-aspirated and mildly boosted range, making it suitable for carbureted performance builds up to roughly 500–600 horsepower depending on fuel demand and system tuning.
