EFI Fuel Adapter Fitting #6 x 3/8 Black

The EFI Fuel Adapter Fitting #6 x 3/8 Black by FRAGOLA is a precision-engineered fuel line connector designed for high-performance fuel systems requiring reliable AN (Army-Navy) standard connections. This straight adapter transitions between 6 AN male fittings and 3/8 inch SAE male quick-disconnect ports, making it an essential component for custom fuel system builds, EFI conversions, and motorsport applications where secure, leak-free fuel delivery is non-negotiable. Whether you're upgrading a classic engine with modern fuel injection or assembling a competition fuel system, this adapter provides the compatibility and durability needed for demanding automotive environments.

Constructed from aluminum and finished in black anodize, the EFI Fuel Adapter Fitting delivers both corrosion resistance and lightweight performance characteristics critical in fuel system plumbing. The black anodized coating protects against oxidation and fuel contamination while maintaining a clean, professional appearance in engine bays and fuel cell installations. The straight configuration eliminates unnecessary bends that could restrict flow or create stress points, while the precision-machined AN and SAE male threads ensure a positive seal with industry-standard quick-disconnect couplers and fuel line adapters. Compact dimensions (1.05 x 1 x 4.1 inches) and minimal weight (0.03 lbs) allow for flexible routing in tight engine compartments without adding significant mass to fuel system assemblies.

This fitting is ideal for fuel injection system retrofits, custom fuel cell plumbing, and high-flow fuel pump installations where AN-to-SAE adapter connections are required. It accommodates both carbureted engine conversions to EFI and original equipment fuel system modifications that demand cross-standard compatibility. Installation is straightforward—thread the 6 AN male end into your fuel system component and connect the 3/8 inch SAE quick-disconnect coupling to your fuel line or pump outlet. The aluminum construction resists vibration-induced loosening, and the anodized finish maintains integrity even when exposed to fuel, heat cycles, and underhood moisture, making it suitable for street, strip, and track environments.
