-6an Holley Carb Fitting 7/8in-20

The Aeromotive -6AN Holley Carb Fitting is a precision straight adapter designed to connect fuel systems to Holley carburetors with exacting dimensional control. This carburetor inlet fitting features a 6 AN male connection on one end and a 7/8-inch-20 male threads on the other, engineered specifically for Holley fuel bowl inlets. Constructed from aluminum and finished in black anodize, this adapter delivers the leak-free integrity required in high-pressure fuel delivery systems.

The straight configuration eliminates unnecessary bends in the fuel line, reducing restriction and turbulence while simplifying installation in tight engine compartments. Black anodized aluminum construction provides corrosion resistance while maintaining lightweight characteristics essential in performance and racing applications. The 6 AN to 7/8-20 thread conversion allows seamless integration with factory and aftermarket Holley carburetor fuel bowls, a critical interface point in EFI upgrades and carbureted engine builds. Precision manufacturing ensures thread fit without leakage under fuel system pressures typical of mechanical fuel pumps and low-pressure electric delivery systems.

This fitting serves street machines, classic car restorations, and vintage hot rod projects where stock Holley carburetors remain the fuel metering choice. Builders transitioning from rubber fuel line to braided stainless steel AN-spec hose systems depend on proper adapter fittings to maintain system integrity and prevent costly leaks during break-in. The adapter is sold individually, allowing builders to source replacement or spare units as needed for multi-carburetor setups or future projects.
