6an Male to 1/2-20 Fuel Pump Adapter Red

The 6AN Male to 1/2-20 Fuel Pump Adapter Red by REDHORSE PERFORMANCE is a precision hose fitting designed for custom fuel system builds and engine modifications where OEM fuel pump outlets require adaptation to -6AN hose standards. This adapter bridges the gap between mechanical fuel pumps with 1/2-20 threaded ports and modern braided fuel line systems, making it essential for engine swaps, carburetor conversions, and aftermarket fuel system installations. Whether you're retrofitting a carbureted engine into a modern chassis or upgrading a classic muscle car with a performance fuel pump, this adapter provides the reliable connection point your fuel delivery system demands.

Constructed from REDHORSE PERFORMANCE's proven aluminum alloy with vibrant red anodizing, this fitting delivers both corrosion resistance and professional appearance in your engine bay. The 6AN male connection accepts standard -6 braided hose (3/8-inch inner diameter), while the 1/2-20 NPT thread on the opposite end screws directly into fuel pump housings common on mechanical pumps and some carbureted fuel delivery systems. The compact 3.8-inch length allows integration into tight engine compartments without requiring excessive hose runs, and the lightweight 0.05-pound construction adds negligible mass to your fuel system plumbing. REDHORSE's anodized finish resists ethanol fuel and engine bay temperatures, ensuring longevity in high-heat environments.

This adapter is ideal for enthusiasts performing engine conversions, EFI retrofits to carbureted platforms, or upgrading to high-flow mechanical fuel pumps that feature 1/2-20 outlet ports. Fabricators and mechanics frequently specify this fitting for street rods, classic restorations, and competition builds where fuel system reliability is non-negotiable. Installation requires only a wrench and basic fuel system knowledge—simply thread onto the pump outlet and connect your -6AN braided hose to the male end using appropriately sized hose clamps or crimp fittings. Verify pump outlet thread size before purchase to confirm 1/2-20 compatibility; cross-reference your pump documentation or measure the existing port threads to ensure correct fit.
