P/C #6 to 9/16-24 Holley Carb Ftgs (2pk)

The P/C #6 to 9/16-24 Holley Carb Ftgs (2pk) is a precision adapter fitting designed for high-performance fuel system integration on carbureted engines running Holley carburetors. These straight-fitting adapters bridge AN-standard fuel lines to traditional Holley carburetor ports, making them essential for builders upgrading fuel delivery systems, retrofitting EFI-to-carb conversions, or plumbing custom fuel rails. Available as a two-pack, this product is ideal for mechanics and enthusiasts tackling fuel system modifications where standardized AN fittings must interface with legacy or performance Holley carb specifications.

Constructed from black anodized aluminum, these fittings deliver corrosion resistance and durability in underhood environments while maintaining a lightweight footprint. The 6 AN male to 9/16-24 inch male configuration provides a secure, leak-free connection through a straight-port design that minimizes turbulence and pressure drop in fuel delivery circuits. Aluminum construction ensures compatibility with both alcohol and gasoline fuel systems, critical for vintage drag builds, street rods, and modern carbureted performance engines where reliability and repeatability are non-negotiable. The anodized finish protects against oxidation and provides a professional appearance in engine bays exposed to heat, moisture, and chemical exposure.

Carburetor fuel system builders benefit most from this two-pack configuration, as dual fittings accommodate primary and secondary fuel inlet ports or allow for redundancy in single-carb setups. Installation requires standard wrench compatibility with both AN and 9/16-24 threads; ensure proper torque specifications and use fuel-grade thread sealant to prevent seepage. These adapters are compatible with all Holley carburetor models featuring 9/16-24 fuel ports, including four-barrel performance carbs, two-barrel economy units, and universal racing carburetors. Whether you're plumbing a vintage muscle car, constructing a custom hot rod, or upgrading an off-road competition engine, this pair streamlines fuel system integration with proven aluminum reliability.
