#6 Ano-Tuff Fuel Press. Gauge Adapter Fitting

The #6 Ano-Tuff Fuel Press Gauge Adapter Fitting by EARLS is a precision instrumentation adapter designed for fuel system diagnostics and monitoring in high-performance and race applications. This straight adapter bridges 3/8 inch NPT male ports to 6 AN male connections while providing a dedicated 1/8 inch NPT gauge port, enabling technicians and tuners to accurately monitor fuel pressure in custom fuel systems. Whether you're building a high-horsepower street rod, motorsports vehicle, or diesel performance platform, this adapter serves as a critical junction point for real-time fuel pressure observation.

Manufactured from aluminum with black anodized finish, this adapter combines corrosion resistance with lightweight construction ideal for engine bay installations. The anodized coating protects against oxidation and fuel degradation while the aluminum construction minimizes weight penalty in applications where every pound matters. The 6 AN male connection meets industry-standard AN hose fittings, ensuring compatibility with modern fuel system components and braided fuel lines commonly found in performance builds. The integrated 1/8 inch NPT gauge port accepts standard mechanical or electronic fuel pressure gauges without requiring bulkhead fittings or additional adapters.

This fitting is essential for anyone upgrading fuel delivery systems, transitioning from OEM fuel rails to aftermarket manifolds, or installing fuel pressure regulators in custom applications. It accommodates both carburetor and fuel-injected systems, making it versatile across engine types and vintage. The compact 1.75 x 1.2 x 3 inch dimensions allow discreet mounting in tight engine compartments, while the straight configuration eliminates flow restrictions. Installation requires standard AN wrench sizes and basic mechanical knowledge; proper thread sealant on NPT ports ensures leak-free operation under varying fuel pressures.
