#6 Fuel Pressure Adapter Black

The AEROQUIP #6 Fuel Pressure Adapter Black (FCM5183) is a straight-threaded gauge adapter designed for fuel system diagnostics and monitoring in high-performance and racing applications. This adapter connects a 6 AN male fitting to a second 6 AN male fitting while providing a 1/8-inch NPT gauge port for direct fuel pressure measurement. Constructed from aluminum and finished in black anodize, it delivers the corrosion resistance and durability required in demanding fuel system environments where pressure verification is critical.

The dual 6 AN male connection maintains consistency with standard fuel line fittings used in custom fuel delivery systems, eliminating adapter incompatibility issues. The 1/8-inch NPT gauge port accommodates industry-standard fuel pressure gauges, allowing real-time monitoring of system pressure during engine operation, tuning, and diagnostics. Black anodizing protects against oxidation in the presence of fuel vapors and moisture, extending service life compared to bare aluminum. Weighing just 0.06 lbs with compact dimensions (2.2 x 1.1 x 3.75 inches), the adapter integrates easily into tight engine bay installations without adding significant weight or bulk.

This adapter is essential for anyone building or troubleshooting a custom or high-performance fuel system. Drag racers, fuel injection tuners, and engine builders rely on direct pressure feedback to validate fuel pump performance, regulator calibration, and injector delivery during development and competition. The straight configuration minimizes turbulence and pressure drop compared to elbowed designs, making it ideal for in-line installation on fuel rails, fuel pressure regulators, or test points. Technicians and enthusiasts performing fuel system diagnostics will find the NPT gauge port invaluable for verifying proper fuel delivery before committing to a full tuning session.

AEROQUIP is recognized in racing and performance circles for precision-engineered fuel system components that withstand extreme pressures and temperatures. This adapter represents the brand's commitment to reliability in competitive and high-output engine applications where fuel delivery consistency directly impacts performance and engine safety.
