Tapered Flare Fitting -10an to -8an

The Aeromotive Tapered Flare Fitting -10AN to -8AN is a precision adapter designed for high-performance fuel system applications where line diameter reduction is required. This fitting serves as a critical transition component in custom fuel delivery systems, particularly in race cars, performance builds, and modified vehicles where AN-sized hose assemblies must interface with smaller diameter fuel rails or carburetors.

The tapered flare design ensures a leak-free seal under pressure, making it essential for builders who demand reliability in demanding fuel system configurations. Engineered by Aeromotive—a leader in fuel system technology—this adapter features a precision-machined tapered flare seat that mates securely with both -10AN (3/4-inch) and -8AN (1/4-inch) JIC 37-degree flare connections. The tapered design eliminates the need for separate reducers in many applications, reducing assembly complexity and potential leak points.

Manufactured to exacting tolerances, the fitting handles fuel system pressures typical of EFI conversions, carbureted race engines, and modified fuel delivery systems without compromise, providing the durability and flow characteristics that serious engine builders expect. This fitting benefits engine builders, fuel system technicians, and enthusiasts performing EFI retrofits or upgrading fuel delivery on high-performance engines. It's particularly valuable when routing larger -10AN supply lines from a fuel pump or regulator to a fuel rail or carburetor.
