The RUSSELL EFI Fuel Fitting 6AN Male to 1/4 Female Black (Part No. 641303) is a precision aluminum adapter designed for high-pressure fuel system applications requiring reliable SAE quick-disconnect coupling. This straight-configuration fitting delivers the flow capacity and durability needed in performance fuel systems, EFI conversions, and custom engine builds where 6 AN line-to-1/4 SAE female adapter compatibility is essential.
Constructed from aluminum with black anodized finish, this adapter resists corrosion and wear while maintaining the low weight critical in performance and racing applications. The 6 AN male thread connects directly to -6 sized fuel lines using standard hose fittings, while the 1/4 inch SAE female quick-disconnect port enables tool-free coupling and uncoupling—a significant advantage during fuel system service, testing, or component swaps. Anodizing provides surface protection without adding significant mass, making this fitting suitable for both street and race fuel system configurations.
This fitting addresses a common integration challenge in EFI retrofits and fuel system upgrades: bridging newer SAE quick-disconnect fuel couplings to traditional 6 AN hard-line systems. Builders, technicians, and enthusiasts rely on RUSSELL adapters for consistent thread engagement, pressure-rated construction, and the mechanical reliability required to prevent leaks under dynamic operating conditions. The compact design (2.55 x 1.6 x 5.7 inches) fits tight engine bay layouts without requiring custom clearancing.
RUSSELL is recognized in the automotive performance and industrial fluid-conveyance sector for manufacturing adapters that meet SAE and AN (Army-Navy) standard specifications. This 6AN-to-1/4 SAE fitting is a single unit (each), allowing replacement of worn couplings or expansion of existing fuel plumbing without ordering bulk quantities. Verify your specific fuel line sizes and quick-disconnect port configuration before ordering to ensure compatibility with your system.
