Fuel Pump Fitting 5/8-18 to 8AN

The Fuel Pump Fitting 5/8-18 to 8AN by ALLSTAR PERFORMANCE is a precision adapter designed for fuel system applications requiring secure connection between 5/8-18 inch male ports and 8AN male fittings. This straight adapter serves as an essential component in fuel delivery systems for performance vehicles, custom fuel systems, and motorsports applications where reliable fuel line integration is critical. Whether you're building a custom fuel system or upgrading an existing setup, this adapter ensures proper thread compatibility and leak-free operation under demanding conditions.

Constructed from durable steel with a zinc oxide finish, the Fuel Pump Fitting 5/8-18 to 8AN provides corrosion resistance and long-term reliability in fuel system environments. The fitting features a crush washer design that creates a positive seal when properly torqued, eliminating potential fuel leaks at the connection point. The straight configuration allows for direct, in-line coupling without space constraints, making it ideal for tight engine bay layouts and fuel tank configurations. The precision machining ensures consistent male threads on both ends, guaranteeing a secure fit with no cross-threading or stripped connections.

This adapter benefits fuel system builders, performance technicians, and motorsports enthusiasts who demand OEM-quality components for custom fuel delivery applications. It's particularly valuable when retrofitting fuel pump assemblies, integrating aftermarket fuel regulators, or connecting fuel tank outlets to AN-standard fuel lines commonly found in race vehicles and high-performance street cars. Installation requires standard wrench tools and proper torque application to the crush washer for optimal sealing. The lightweight design at 0.14 lbs adds minimal weight to fuel system assemblies while maintaining the structural integrity necessary for high-pressure fuel delivery systems.
