The #6 to 1/4 NPT Fuel Pressure Adapter with 1/8 NPT Port (Part #700193) is a precision straight-fitting gauge adapter engineered for high-pressure fuel system diagnostics and installation. This aluminum adapter transitions from a #6 AN male port to a 1/4 inch NPT male port while incorporating a 1/8 inch NPT gauge port, making it an essential component for technicians and enthusiasts working with custom fuel systems, high-performance engine builds, and fuel pressure monitoring applications. The red anodized aluminum construction provides corrosion resistance and durability in demanding automotive and motorsport environments.
The straight-fitting design eliminates unnecessary bends in fuel line routing, promoting efficient fuel flow and reducing turbulence in sensitive fuel delivery systems. The 1/8 NPT gauge port allows direct connection of fuel pressure gauges or sensors without requiring secondary adapters, streamlining system installation and improving measurement accuracy. The combination of AN and NPT threading accommodates modern fuel injection systems that commonly mix both thread standards. This adapter's compact footprint—2.7 x 1.2 x 3.65 inches—fits tight engine bay layouts without interfering with surrounding components.
Fuel system builders, race car technicians, and performance engine developers depend on this adapter when installing aftermarket fuel regulators, upgrading fuel pressure systems, or adding diagnostic instrumentation. Its aluminum construction keeps weight minimal while maintaining pressure rating integrity—critical for applications ranging from street-tuned vehicles to dedicated track cars. The red anodized finish provides visual distinction in color-coded fuel system configurations and resists oxidation in high-vibration, high-temperature engine compartments.
Whether you're upgrading a fuel delivery system, installing a fuel pressure gauge for real-time monitoring, or building a custom engine setup, this AN-to-NPT transition adapter bridges the gap between different fuel system component standards with proven reliability.
