#6 to #6 Fuel Press Adapter w/ 1/8 NPT Port

The #6 to #6 Fuel Press Adapter w/ 1/8 NPT Port from XRP-XTREME RACING PROD. is a precision fitting engineered for fuel system monitoring and diagnostics in performance and modified vehicles. This straight adapter connects two 6 AN male ports while integrating a 1/8 inch NPT gauge port, allowing you to install a fuel pressure gauge without interrupting primary fuel lines. Mechanics and tuners rely on this type of adapter when upgrading fuel systems, troubleshooting pressure issues, or maintaining real-time visibility into fuel delivery during high-performance driving or dyno testing.

Built from lightweight aluminum and finished in vibrant red anodizing, the #6 to #6 Fuel Press Adapter delivers corrosion resistance and durability in fuel-saturated environments. The straight body design minimizes turbulence and pressure loss, critical for accurate gauge readings and consistent fuel delivery under boost or high RPM conditions. The integrated 1/8 NPT gauge port accepts standard mechanical or electronic fuel pressure gauges, enabling quick installation without fabrication or welding; the aluminum construction keeps weight minimal while providing the strength required for systems running elevated fuel pressures in turbocharged, supercharged, or injected applications.

This adapter is ideal for engine builders, drag racers, and street tuners who need reliable pressure monitoring on carbureted fuel systems, EFI conversions, or upgraded fuel rails. Installation is straightforward—thread the gauge port and connect both 6 AN lines using standard -6 fittings and hose, making it compatible with any system already standardized on 6 AN plumbing. The compact footprint (2.7 x 1.2 x 3.65 inches) fits tight engine bays without requiring extensive rerouting, and the proven XRP design ensures leak-free operation across ambient conditions and high-cycle applications.
