The Vibrant Performance -8AN Flare to AN Straight Cut Thread (9/16-18) adapter is an essential component for custom fuel injection setups, turbo upgrades, and high-performance engine modifications. This adapter connects legacy flare-style fuel lines to modern AN-threaded components, making it ideal for builders transitioning from carburetor-era plumbing to contemporary fuel delivery systems.
Designed for reliability, the -8AN designation indicates a nominal 1/2-inch inner diameter on the flare side, while the 9/16-18 straight-cut thread conforms to the AN standard (JIC). Vibrant Performance's precision machining ensures a clean flare seat cut, preventing galling or deformation, which is critical for maintaining fuel system integrity under high-pressure conditions.
This adapter is particularly beneficial for those retrofitting classic engines with fuel injection or upgrading fuel pressure regulators. Its compact design minimizes engine bay clutter while providing a robust sealing surface, ensuring reliable connections in applications running fuel pressures above 50 psi.
