The #6AN fitting from EDELBROCK is a precision adapter designed for high-flow fuel and fluid line applications in performance and modified vehicles. This straight 6 AN male to 5/8-20 male adapter serves as a critical junction point in custom fuel systems, carburetor conversions, and aftermarket fuel injection setups where standardized AN fittings must interface with legacy or specialized ports. Built for automotive enthusiasts and mechanics who demand reliability in modified fuel delivery systems, this adapter eliminates leaks and maintains system integrity under pressure.
Constructed from aircraft-grade aluminum and finished in red anodized coating, the #6AN fitting resists corrosion and oxidation in engine bay environments where temperature fluctuations and fuel vapors pose durability challenges. The 6 AN (AN06) designation indicates a 3/8-inch inner diameter hose bore—standard for mid-range fuel flow applications in V8 engines and fuel-injected builds. The straight configuration eliminates 90-degree bends, reducing pressure drop and turbulence in fuel lines while simplifying installation in tight engine compartments. Red anodizing provides both protection and visual identification, allowing technicians to quickly identify AN-spec components during system diagnostics or modifications.
Mechanics and hot rodders commonly employ this adapter when retrofitting carbureted engines with modern fuel systems, upgrading OEM fuel delivery on LS swaps, or building custom fuel pressure regulators and distribution blocks. Compatibility spans carburetors with SAE 5/8-20 inlet threads—a legacy standard on many classic and aftermarket units—paired with modern AN hose assemblies and components. Installation requires standard wrench sizes and hand-tight plus 1/4-turn methodology to seat the O-ring seal without over-torque. Proper sizing ensures the adapter won't become a flow restriction in systems demanding consistent pressure delivery above 40 PSI, making it essential for fuel-injected conversions and turbocharged applications.
