Fuel Injection Fitting 14mm-1.50 to -6

The Allstar Performance Fuel Injection Fitting 14mm-1.50 to -6 AN is a precision adapter designed for fuel system builders, engine tuners, and performance mechanics who require reliability in high-pressure injection environments. This fitting connects metric threaded fuel rails to standard AN (Army-Navy) hose connections, making it essential for custom fuel system integration on turbocharged, supercharged, and carbureted race engines.

Featuring a 14mm x 1.50 metric thread on one end and a -6 AN port on the other, this adapter ensures compatibility with common fuel rail configurations while maintaining proper line sizing for optimal fuel flow dynamics. The construction is designed to resist corrosion and fuel degradation, which is critical for maintaining system integrity over extended engine runtime and during seasonal storage.

Performance builders favor this Allstar fitting for custom fuel system layouts on LS engines, small-block Chevys, Ford modular platforms, and Mopar builds where metric fuel rails are paired with aftermarket components. This fitting is ideal for those looking to upgrade their fuel systems for enhanced performance and reliability.
