Push-On EFI Fitting #6 to 3/8in Hard Tube Black

The Push-On EFI Fitting #6 to 3/8in Hard Tube Black is a precision fuel system adapter engineered for electronic fuel injection applications requiring reliable, secure connections between different line sizes. This straight-configuration fitting serves technicians, performance builders, and fuel system integrators who need a dependable transition from 6 AN male ports to 3/8 inch SAE female quick-disconnect outlets. Whether you're installing a fuel rail, routing fuel lines through an engine bay, or assembling a custom fuel delivery system, this adapter provides the exact port compatibility needed to connect components with mismatched AN and SAE specifications.

Manufactured by Russell, a trusted name in fuel system engineering, this fitting is constructed from aluminum and features black anodized finishing for corrosion resistance and durability in engine compartment environments. The straight design eliminates elbows or complex routing, allowing direct connection between hard tube fuel lines and quick-disconnect couplers with no flow disruption or turbulence. The male 6 AN thread on one end engages securely with female ports, while the 3/8 inch SAE female quick-disconnect end accepts standard push-on fuel line couplers, ensuring leak-free operation under pressure and vibration. Black anodizing protects against oxidation and provides a clean, professional appearance in visible installations.

This fitting is ideal for EFI fuel systems, aftermarket fuel rails, fuel distribution blocks, and custom fuel delivery setups where hard tube lines transition to quick-disconnect couplers. Installation requires no special tools—simply thread the 6 AN male end into the receiving port and attach fuel line tubing to the 3/8 inch SAE female quick-disconnect side. Verify thread sizes before installation to ensure proper engagement and eliminate risk of cross-threading. Weighing just 0.08 lbs, it adds minimal bulk while delivering robust performance in high-pressure fuel applications.
