6AN Male 3/8in Push on EFI Blue

The 6AN Male 3/8in Push on EFI Blue from REDHORSE PERFORMANCE is a precision fuel line adapter engineered for modern EFI engine builds and fuel system upgrades. Designed for mechanics and enthusiasts upgrading fuel delivery systems on turbocharged, supercharged, or naturally aspirated platforms, this connector bridges legacy 3/8-inch push-on fuel lines to modern 6AN hose fittings—a critical transition fitting when integrating aftermarket fuel injectors, fuel rails, or high-flow fuel regulators into vehicles originally equipped with rubber fuel lines.

This male adapter features a 6AN thread port for secure attachment to EFI fuel system components while the 3/8-inch push-on end accommodates original or replacement rubber fuel hoses without requiring barbed fittings or hose clamps. The vibrant blue anodized aluminum body provides both corrosion resistance and easy identification within complex fuel systems, preventing cross-connection errors during assembly or maintenance. The compact design (14.8 x 3.85 x 0.85 in overall) minimizes installation footprint in tight engine bays, while the lightweight construction (0.055 lbs) integrates seamlessly into both street and track-oriented fuel system architectures.

Professional mechanics and home builders benefit most when retrofitting carbureted or older fuel-injected vehicles with modern EFI systems, or when upgrading factory fuel delivery on late-model platforms handling higher boost pressures. This adapter is essential for fuel pump upgrades and ensures compatibility with a wide range of aftermarket components.
