90 Degree -6AN Male to 5/16in EFI Line

The 90 Degree -6AN Male to 5/16in EFI Line adapter is a precision fuel system fitting designed for high-performance EFI (Electronic Fuel Injection) applications where space is limited or specific directional flow is required. This adapter bridges the gap between -6AN (AN6) male connections and 5/16-inch SAE female quick disconnect ports, making it essential for custom fuel line routing, engine conversions, and aftermarket fuel system installations. Whether you're building a street machine, race vehicle, or restoring a classic with modern fuel management, this 90-degree elbow fitting ensures proper fuel delivery without kinks or pressure loss.

Constructed from aluminum and finished in black anodized coating, the 90 Degree -6AN Male to 5/16in EFI Line adapter resists corrosion while maintaining a lightweight profile—critical in performance applications where system weight matters. The anodized finish provides superior durability against fuel, moisture, and thermal cycling, ensuring reliable long-term performance in demanding engine bay environments. The 90-degree angle orientation allows builders to optimize fuel line paths around engine components, firewall penetrations, and fuel rail configurations without unnecessary hose bends that can restrict flow or create turbulence. The compact 3.54 x 0.75 x 6.3-inch dimensions and 0.07 lb weight make this fitting ideal for tight engine compartments where space efficiency is non-negotiable.

This fitting is ideal for fuel system fabricators, EFI conversion specialists, and performance enthusiasts building custom fuel delivery systems on LS-swap builds, carbureted-to-EFI conversions, or high-flow fuel rail assemblies. The SAE female quick disconnect end allows tool-free fuel line coupling and disconnection for maintenance or component swaps, while the -6AN male end ensures SAE J518 Code 61 standardized connections with industry-standard braided hose fittings. Proper installation requires compatible -6AN hose or tubing on the male end and 5/16-inch quick-connect fuel line on the female end; always verify port thread pitch and disconnect coupling compatibility before assembly.
