Fuel Press.Gauge Fitting

The MOROSO Fuel Pressure Gauge Fitting (Part Number 65360) is a precision adapter designed to connect fuel pressure gauges to fuel systems with industry-standard hose barb and NPT gauge port configurations. This straight-through fitting enables accurate pressure monitoring in high-performance fuel systems, engine test stands, and fuel delivery diagnostics where real-time gauge feedback is critical to tuning and troubleshooting.

The adapter features dual 3/8-inch hose barb ports for primary fuel line integration and a 1/8-inch NPT port for gauge connection, allowing straightforward plumbing into existing fuel rails and regulator outlets. Constructed from black anodized aluminum, the fitting resists corrosion and provides a lightweight, durable connection point. The straight configuration eliminates flow restrictions and simplifies installation in confined engine bay spaces where bend-radius clearance is limited. Anodized aluminum construction offers superior longevity compared to bare aluminum or brass alternatives when exposed to fuel and moisture.

This fitting serves builders, tuners, and technicians who require reliable pressure monitoring during fuel system upgrades, carburetor conversion projects, or engine dyno testing. It's commonly used on street machines, race cars, marine fuel systems, and automotive test benches where gauge readings inform fuel pressure regulator adjustment and fuel pump performance verification. The standardized 3/8-inch hose barb and NPT gauge port sizes ensure broad compatibility with aftermarket fuel system components.

MOROSO is recognized within the automotive performance market for fuel system plumbing and measurement accessories. The gauge fitting adapter is a foundational piece for anyone installing remote fuel pressure monitoring—a standard practice when troubleshooting lean-running conditions, verifying fuel pump output, or optimizing carburetor fuel delivery during engine development.
