#6 > 9/16-24 Holley

The #6 > 9/16-24 Holley adapter fitting from EARLS is a precision straight adapter designed to bridge 6 AN male and 9/16-24 inch male connections in high-performance fuel systems and hydraulic applications. This fitting serves as a critical transition component for builders and technicians who need to integrate legacy Holley carburetors or fuel system components with modern AN-standard hoses and fittings. The compact aluminum construction makes it ideal for tight engine bay installations where space is at a premium.

Constructed from lightweight aluminum and finished with blue anodized coating, the #6 > 9/16-24 Holley adapter combines corrosion resistance with clean aesthetics while maintaining structural integrity under pressure. The straight configuration eliminates unnecessary bends, reducing turbulence and potential leak points in fuel or coolant lines. EARLS fittings are engineered to precision tolerances, ensuring secure, leak-free connections that meet competition and street performance standards. The anodized finish not only protects against oxidation but also allows builders to maintain a professional appearance in show-quality engine bays.

This adapter is essential for vintage hot rod builds, fuel system upgrades, and custom carbureted engines where Holley components are being modernized with AN plumbing. The 6 AN male connection accepts standard braided hose fittings, while the 9/16-24 inch male thread directly engages Holley fuel bowl inlet fittings and related legacy equipment. Installation is straightforward—simply thread the 9/16-24 end into the Holley component and connect your 6 AN hose assembly to the opposite end. Weighing just 0.02 lbs, the compact footprint fits in confined spaces without adding weight to the fuel system.
