Fuel Rail Quick Connect Fitting -6AN to 3/8 Tube

The Fuel Rail Quick Connect Fitting -6AN to 3/8 Tube by ICT BILLET is a precision aluminum fuel line adapter engineered for high-performance fuel injection systems, custom fuel rails, and aftermarket engine builds. Operators and builders who demand reliability under pressure rely on quick-disconnect fittings to simplify fuel system assembly, maintenance, and field serviceability. This straight-pattern adapter bridges the gap between 6 AN male connections and 3/8 inch SAE female quick-disconnect ports, making it essential for turbocharged, supercharged, and naturally aspirated performance platforms.

Manufactured from billet aluminum and finished in black anodized coating, this fitting combines corrosion resistance with lightweight construction—critical attributes in high-vibration engine bays and demanding operational environments. The 6 AN to 3/8 SAE configuration ensures proper fuel flow velocity and pressure containment across racing, military vehicle, and specialty applications. Black anodizing protects against oxidation while maintaining a low-profile aesthetic consistent with professional fuel system standards. The straight geometry minimizes turbulence and pressure drop, preserving system efficiency and fuel atomization at the injector rail.

This fitting suits builders integrating aftermarket fuel rails, swapping fuel system components, or upgrading fuel delivery on vehicles subjected to sustained high load or duty cycles. The quick-disconnect design allows rapid disconnect for fuel system flush, injector service, or emergency fuel isolation—practical for field maintenance in remote or austere environments. Weighing just 0.04 lbs with compact dimensions of 1.5 x 0.95 x 3 inches, it installs in tight engine compartments without sacrificing structural integrity. Compatibility spans domestic and import platforms using SAE quick-disconnect fuel couplers and AN-spec fuel rails, making it a versatile addition to any performance or military-spec fuel system upgrade.
