#6 ORB to 3/8 Male Q/C EFI Fitting Straight

The #6 ORB to 3/8 Male Q/C EFI Fitting Straight from FRAGOLA is a precision fuel system connector engineered for modern EFI engine builds and high-performance fuel injection systems. Whether you're upgrading a carbureted classic to fuel injection, tuning a street rod, or assembling a competition engine, this adapter bridges ORB (O-Ring Boss) fuel lines to quick-connect fittings with rock-solid reliability. Mechanics and fabricators rely on FRAGOLA fittings because they eliminate leaks, simplify fuel line assembly, and maintain system integrity under pressure.

This straight fitting connects a #6 ORB female port to a 3/8-inch male quick-disconnect coupling, allowing seamless integration with standard EFI fuel rails, regulators, and distribution blocks. The straight configuration eliminates bends and reduces turbulence in fuel flow, maintaining consistent pressure delivery to injectors across all RPM ranges. FRAGOLA's precision-machined construction and chromed finish resist corrosion and withstand the vibration found in engine bays, while the O-ring seal design creates a leak-free connection without thread sealant tape. The compact 3.1 x 2.25 x 5.9-inch form factor fits tight engine compartments, and at just 0.07 lbs, adds negligible weight to your fuel system.

Street rod builders, EFI retrofit specialists, and performance engine shops specify this fitting for its compatibility with Holley, Edelbrock, and other major fuel rail and regulator brands that use ORB ports. Installation requires no special tools—hand-tighten the ORB connection and snap the quick-disconnect into place. This adapter is ideal for fuel systems operating in the 40–60 PSI range typical of modern EFI engines, making it suitable for naturally aspirated, supercharged, and turbocharged applications alike. Keep one in your shop for emergency repairs or fuel system modifications.
