6AN Male to 5/16in SAE Quick Disconnect Male

The 6AN Male to 5/16in SAE Quick Disconnect Male fitting from REDHORSE PERFORMANCE is an essential adapter for fuel system builders, performance technicians, and serious modifiers who demand reliable connections in custom fuel delivery setups. This adapter bridges two industry-standard connection types—the compact 6AN hose fitting and the traditional 5/16-inch SAE quick-disconnect interface—allowing seamless integration between modern AN fuel lines and legacy fuel system components. Whether you're upgrading a carbureted engine's fuel delivery, adapting aftermarket fuel pumps, or consolidating mismatched fuel line standards in a restomod, this compact adapter eliminates the need for multiple fittings or custom fabrication.

Engineered with precision machining and corrosion-resistant materials, the 6AN Male to 5/16in SAE Quick Disconnect Male fitting ensures leak-free operation under fuel system pressure and vibration. The male 6AN end accepts standard -6AN hose with JIC swaged fittings, while the 5/16-inch SAE quick-disconnect male end provides a reliable, quick-connect interface for fuel lines, tanks, or carburetors using SAE specifications. The compact footprint—measuring just 2.835 inches long and weighing 0.074 pounds—fits tight engine bays without compromising flow or creating bulky junction points. This fitting's dual-thread design ensures full engagement, preventing accidental disconnection during hard acceleration or track use where vibration is constant.

Mechanics and performance builders rely on this adapter when retrofitting fuel systems across mixed-specification applications—classic cars with modern pump upgrades, race vehicles with staged fuel injection, or street machines combining OEM and aftermarket components. Installation is straightforward: thread the 6AN male end directly into your hose assembly, then connect the SAE quick-disconnect end to your fuel source or distribution component. Verify fuel line compatibility with AN hose specifications and ensure all connections are torqued to manufacturer standards to guarantee system integrity under full boost or extended runtime.
