Constructed to exacting standards, the 6AN - 9/16in x 24 Holley Single Feed Carb Fitting features a 6AN port size that accepts standard 6AN braided fuel line, paired with a 9/16-inch by 24-thread inlet that threads directly into Holley carburetor fuel bowls. The compact design—measuring just 2.8 inches in length—minimizes packaging constraints in tight engine bays while maintaining full flow capacity. Engineered from durable materials to resist fuel degradation and vibration-induced loosening, this fitting is built to integrate seamlessly into both traditional carb setups and EFI-to-carb conversion applications where original equipment adapters are unavailable or incompatible.

Installation is straightforward: thread the 9/16x24 end into the carburetor fuel inlet port and connect your 6AN fuel line to the opposite end using a standard 6AN hose barb or fitting. Mechanics and fabricators appreciate the reliability of REDHORSE PERFORMANCE components, which are manufactured to OEM tolerances and tested for durability in both street and strip applications. Weighing just 0.055 pounds, this lightweight adapter adds negligible mass while delivering the fuel system integrity that performance engines demand.
