6AN to 5/16in SAE Quick Disconnect Female 90Deg

The 6AN to 5/16in SAE Quick Disconnect Female 90Deg fitting from REDHORSE PERFORMANCE is an essential adapter for high-flow fuel and hydraulic system installations on modified vehicles. This 90-degree angle connector bridges the gap between modern -6AN (11/16-16 UN) hose standards and legacy 5/16-inch SAE quick disconnect couplers, making it ideal for retrofitting carbureted engines, classic fuel system upgrades, and aftermarket fuel pressure regulators. Whether you're converting a vintage carb setup to EFI, integrating a fuel cell, or plumbing a custom hydraulic line, this fitting eliminates the need for custom hose fabrication and provides a reliable, leak-free connection point.

Constructed with precision engineering, the 90-degree orientation saves critical engine bay real estate by directing flow at a right angle, preventing interference with headers, intake manifolds, or tight underhood layouts common in performance builds. The female quick disconnect end accepts standard 5/16-inch SAE male quick couplers, allowing you to break connections without spilling fluid—critical when servicing fuel systems or swapping components on the fly. REDHORSE PERFORMANCE fittings are manufactured to strict tolerances with durable materials rated for high-pressure applications, ensuring compatibility with fuel systems running 60+ PSI and protecting against vibration-induced leaks on track or street machines. The compact 2.84 x 1.41 x 4.42-inch package and minimal 0.125 lb weight integrate seamlessly into space-constrained engine compartments without adding unnecessary bulk.

Mechanics and performance enthusiasts tackling EFI conversions, fuel cell installations, or hybrid hydraulic systems benefit most from this adapter's versatility and proven durability. It works equally well for fuel delivery, return-line management, and auxiliary pressure lines on turbocharged or supercharged applications where plumbing flexibility is non-negotiable. Installation is straightforward: thread the -6AN side into your modern hose or component, secure the 5/16-inch SAE female coupler to legacy or aftermarket quick disconnects, and torque appropriately for your system's PSI rating. For street rods, restorations, race cars, and daily-driven modified vehicles requiring seamless cross-standard connectivity, this REDHORSE fitting delivers the reliability and compact form factor that separates amateur builds from professional-grade installations.
