#6 to 1/2-20 Inv Flare Fuel Pump Fitting

The #6 to 1/2-20 Inv Flare Fuel Pump Fitting (XRP702006) is a critical adapter component for custom fuel system installations, designed to bridge modern AN-style fuel lines with legacy inverted flare connections common in carbureted engines and vintage fuel pump assemblies. This straight adapter fitting serves enthusiasts and professional mechanics building high-performance fuel delivery systems where AN line standards must integrate with existing OEM or custom hardline infrastructure. Whether you're upgrading a classic muscle car fuel system, installing an aftermarket fuel pump on a hot rod, or adapting fuel system components across different generations of vehicles, this fitting ensures secure, leak-free connections.

Machined from aluminum and finished with red anodization for corrosion resistance, the #6 to 1/2-20 Inv Flare Fuel Pump Fitting features a 6 AN male port on one end and a 1/2-20 inverted flare male connection on the other. The straight design eliminates unnecessary elbows in tight engine bays, reducing pressure drops and simplifying routing. The inverted flare geometry creates a compression-sealed connection that remains reliable under fuel system pressures and vibration, while the aluminum construction keeps weight minimal—critical in performance builds. Red anodizing protects against corrosion from fuel exposure and environmental moisture, extending service life in both street and racing applications.

This adapter is essential for builders transitioning between modern fuel line standards and carbureted or older fuel pump configurations, including classic Chevy, Ford, and Mopar platforms where 1/2-20 inverted flare threads remain standard. Installation requires only basic hand tools and a wrench; ensure both connections are fully seated and tightened to prevent fuel leaks. Verify your fuel system pressure rating matches your pump specification, as inverted flare connections are rated for typical carburetor fuel pressures (4–7 psi) and should be replaced if corrosion or thread damage develops.
