Fuel Pump SBC 7.5-9.0 3/8in In/Out

The Fuel Pump SBC 7.5-9.0 3/8in In/Out by Allstar Performance is a high-flow mechanical fuel pump engineered for Small Block Chevrolet engines and carbureted applications. This pump addresses a critical need in street, strip, and restoration builds where reliable fuel delivery directly impacts engine performance and consistency. Whether you're running a classic muscle car, a vintage hot rod, or a custom project, a quality mechanical fuel pump ensures steady fuel supply across varying engine speeds and loads without the complexity of an electric system.

Built with precision casting and engineered internals, the Fuel Pump SBC 7.5-9.0 delivers 7.5 to 9.0 PSI output—the sweet spot for carbureted engines and many fuel-injected retrofit builds. The 3/8-inch inlet and outlet ports accommodate standard fuel line sizes, allowing straightforward installation into existing fuel systems or new custom setups. Allstar Performance's reputation for durability means this pump features robust diaphragm design and corrosion-resistant construction, reducing the risk of fuel system failure during extended driving sessions or high-performance use.

Mechanics and engine builders favor this pump for SBC engine swaps, carburetor conversions, and restorations where original equipment is unavailable or undersized. Compact dimensions and lightweight design (1.91 lbs) make it easy to mount on the block or frame without requiring special brackets or modifications. Installation on most SBC platforms—including Chevy 350, 383, 427, and stroker variants—is straightforward, making it ideal for DIY enthusiasts and professional shops alike who demand proven reliability and consistent flow rates.
