EFI Fuel Fitting 6an Male to 1/4 Female Blue

The EFI Fuel Fitting 6AN Male to 1/4 Female Blue from Russell is a critical adapter for modern EFI fuel system installations and upgrades. This straight-port fitting bridges the gap between 6 AN hose connections and 1/4 inch SAE female quick disconnect ports, making it essential for fuel system customization on late-model vehicles, fuel injection retrofits, and high-performance engine builds. Whether you're plumbing a fuel cell, upgrading a carburetor-to-EFI conversion, or integrating aftermarket fuel components, this adapter ensures leak-free connections under pressure.

Constructed from aluminum and finished in blue anodized coating, the Russell 6AN to 1/4 SAE adapter delivers durability and corrosion resistance in underhood environments. The straight-port design minimizes turbulence and pressure loss compared to 90-degree alternatives, preserving fuel delivery efficiency and pump longevity. The 6 AN male thread engages securely with standard braided fuel hose barbs or compression fittings, while the 1/4 inch SAE female quick disconnect port accepts universally compatible quick-couplers used on fuel rails, regulators, and distribution blocks. Anodized aluminum resists oxidation and maintains structural integrity under sustained fuel system pressure.

This fitting is ideal for fabricators, engine builders, and DIY enthusiasts upgrading fuel delivery systems on street rods, track cars, and late-model swaps. Technicians appreciate the compatibility with both new EFI harnesses and legacy quick-disconnect standards, reducing sourcing complexity on mixed-component builds. Compact at 2.65 by 1.65 by 4.95 inches and weighing just 0.08 pounds, it fits tight engine bays without interference. Ensure fuel line sizing matches 6 AN specifications and verify quick-disconnect gender before installation to guarantee pressure-tight operation throughout the fuel system.
