Fuel Pressure Gauge Carb 0-15psi

The Fuel Pressure Gauge Carb 0-15psi from FUELAB FUEL SYSTEMS is an essential diagnostic and tuning tool for carburetor-equipped engines, street machines, and classic car restorations. Designed for mechanics and enthusiasts who demand precision fuel system monitoring, this analog gauge provides real-time visibility into fuel delivery pressure—critical data for diagnosing weak pumps, leaking regulators, and carburetor starvation issues. Whether you're troubleshooting a stumbling idle, validating a new fuel system upgrade, or verifying that your carburetor receives adequate supply pressure, this mechanical gauge delivers immediate feedback without electronic complexity.

This full-sweep mechanical gauge features a white face with clear 0-15 psi calibration, ideal for carbureted applications where fuel pressure typically ranges from 4 to 8 psi for standard Holley, Edelbrock, and vintage designs. The 1.5-inch diameter housing mounts cleanly in engine bays, dashboards, or auxiliary gauge panels, while the mechanical design eliminates the need for electrical connections—ensuring reliable operation in high-vibration environments and hot underhood conditions. The analog needle response is immediate and accurate, giving you instantaneous pressure readings without lag, making it invaluable for load-bearing diagnostics during acceleration, cruise, and part-throttle operations.

Carburetor enthusiasts, drag racers, and vintage engine builders rely on this gauge to validate fuel system performance during initial startup, tuning refinement, and long-term maintenance. Installation requires a simple 1/8-inch NPT or 1/4-inch NPT tee fitting in the fuel line between the pump and carburetor inlet; many builders incorporate it alongside a fuel pressure regulator for fine-tuned control. The compact, lightweight design (0.14 lbs) integrates easily into tight engine compartments, and the white-face contrast ensures readability in all lighting conditions—from garage benches to sunlit dyno sessions.
