8AN ORB Male to 3/8in Push on EFI Black

The 8AN ORB Male to 3/8in Push on EFI Black fitting from REDHORSE PERFORMANCE is engineered for builders and mechanics upgrading fuel delivery systems on modern EFI engines. This adapter bridges the gap between AN-spec hard-line fuel rails and push-to-connect fuel hoses, making it essential for custom fuel system installations, engine swaps, and performance fuel pump upgrades. Whether you're tuning a naturally aspirated engine or building a turbocharged platform, this fitting delivers the reliability and compatibility your high-flow fuel system demands.

Constructed with precision machining and anodized black finish, the 8AN ORB male thread ensures secure connection to fuel rails and manifolds while the 3/8-inch push-on barb accommodates standard EFI hose sizes without the need for hose clamps in most applications. The O-ring boss (ORB) design seals reliably under fuel system pressure, preventing leaks that compromise engine performance and safety. REDHORSE PERFORMANCE's reputation for durability in motorsports ensures this adapter withstands vibration, thermal cycling, and the corrosive environment of modern fuel blends, making it a trusted choice for serious engine builders.

This fitting is ideal for fuel system integrators upgrading carbureted engines to EFI, retrofitting vintage platforms with modern fuel delivery, or fine-tuning fuel line routing on race-prepped vehicles. The compact 2.835-inch overall length facilitates tight engine bay installations where space is critical. Installation is straightforward—thread the 8AN male into your fuel rail or pump manifold, then push your 3/8-inch hose onto the barb until it seats fully, ensuring a tight seal for pressurized fuel systems operating at typical EFI pressures up to 60 PSI and beyond with proper hose selection.
