#10 Male Port to #10 Adapter Fitting

The #10 Male Port to #10 Adapter Fitting (MP-3063) from MAGNAFUEL/MAGNAFLOW FUEL SYSTEMS is a precision gauge adapter designed for fuel system diagnostics and monitoring. This straight adapter connects two #10 AN male ports while incorporating dual 1/8 inch NPT gauge ports, making it an essential component for fuel pressure measurement, fuel flow verification, and system troubleshooting in performance and race fuel systems.

Constructed from aluminum with a purple anodized finish, the adapter offers corrosion resistance and easy identification in the engine bay. The O-ring sealed #10 AN connections ensure leak-free performance under high-pressure fuel system conditions, while the dual gauge ports allow simultaneous monitoring of fuel pressure and temperature via separate instruments. The adapter arrives complete with a protective plug, preventing contamination when gauge ports are not in use. This configuration is critical for fuel system tuning, where real-time pressure feedback directly influences fuel pump performance, injector spray patterns, and overall engine management accuracy.

This adapter is used in aftermarket fuel system installations, custom fuel rail builds, engine swaps, and dyno testing environments where precise fuel pressure data is non-negotiable. Performance builders, fuel system technicians, and engine tuners rely on adapters like this to isolate diagnostic points and validate system performance before full vehicle integration. The compact, lightweight design integrates seamlessly into tight engine compartment layouts without compromising accessibility.

AN fitting adapters are foundational to fuel system diagnostics and remain standard across OEM performance platforms and aftermarket fuel system manufacturers. The #10 AN standard provides the flow capacity needed for high-horsepower applications while maintaining compact port sizing for gauge mounting flexibility.
