EFI Adapter Fitting -6an Male to 3/8in SAE Quick

The Russell EFI Adapter Fitting -6AN Male to 3/8in SAE Quick is a precision fuel injection adapter designed to connect AN-sized fuel system components to quick-connect couplings found in modern EFI (Electronic Fuel Injection) installations. This straight adapter transitions a 6 AN male port to a 3/8-inch SAE female quick-disconnect, making it essential for custom fuel system builds, hot rods, motorsports applications, and any high-performance engine conversion requiring reliable fuel line management.

Built from aluminum with blue anodized finish, this fitting combines lightweight construction with corrosion resistance—critical properties for fuel systems where vibration, temperature fluctuation, and moisture exposure are constant concerns. The 6 AN male thread (standard in performance fuel systems) mates securely with AN hose fittings, while the 3/8-inch SAE quick-disconnect side accepts industry-standard fuel couplers used in many late-model EFI conversions. The straight configuration eliminates unnecessary bends, reducing turbulence and pressure drop in the fuel line, which supports consistent fuel delivery to the injectors.

This adapter serves engine builders, restoration shops, and enthusiasts performing fuel system upgrades on vehicles transitioning from carburetion to EFI. Whether adapting a classic car to modern fuel injection, installing an aftermarket EFI kit on a race engine, or troubleshooting fuel line incompatibilities in a custom build, this Russell fitting provides the secure, leak-free connection necessary for reliable performance. The compact dimensions (2.7 x 1.25 x 5 inches) and minimal weight (0.07 lbs) integrate easily into tight engine bay layouts without adding stress to adjacent fuel lines.

Russell has long been recognized in the high-performance fuel system segment for precision-engineered adapters and fittings that meet the demands of competitive motorsports and street performance applications. This particular adapter addresses a common compatibility gap between legacy SAE quick-connect systems and modern AN fuel system standards, making it a practical solution for mixed-specification fuel installations.
