#6 x 5/8-20 Carb Adapter Black

The #6 x 5/8-20 Carb Adapter Black from Russell is a critical fitting for automotive fuel system modifications and carburetor plumbing configurations. This straight adapter connects AN male ports to standard 5/8-20 male threads, making it essential for builders transitioning between braided fuel lines and traditional carbureted engine setups. Whether you're restoring a classic hot rod, upgrading a street machine, or fabricating a custom fuel delivery system, this adapter bridges incompatible thread standards without compromise.

Constructed from black anodized aluminum, the #6 x 5/8-20 Carb Adapter delivers corrosion resistance and durability in underhood environments while maintaining a clean, finished appearance on exposed fuel system builds. The anodized finish protects against oxidation and fuel seepage, critical factors in long-term reliability. The straight design minimizes turbulence in fuel flow while the precise machining ensures leak-free seated connections. Russell's reputation for precision-engineered fuel system components means this adapter meets OEM standards for pressure and flow characteristics, suitable for both carbureted and EFI retrofit applications.

Mechanics and serious enthusiasts benefit from this adapter when upgrading fuel delivery on vintage carburetor engines or converting to modern braided fuel line systems. Installation is straightforward—thread the 5/8-20 male end into carburetor fuel inlet fittings or aftermarket fuel pressure regulators, then connect your #6 AN braided hose to the male AN port. Its compact 2.65-inch length ensures it fits tight engine bays and complex plumbing layouts. Always verify carburetor and regulator thread specifications before purchase to ensure proper fitment.
