Fuel Pressure Gauge 0-15 PSI

The Fuel Pressure Gauge 0-15 PSI by Racing Power Co-Packaged is a mechanical analog instrument designed for engine builders, mechanics, and automotive enthusiasts who need reliable real-time fuel system monitoring. This full-sweep gauge delivers critical pressure data for carburetor-fed and fuel-injected engines, helping diagnose fuel delivery problems, verify fuel pump performance, and ensure optimal engine operation during tuning and troubleshooting.

Built as a mechanical analog instrument with a 1-1/2 inch black face dial, this gauge features a full sweep needle movement for immediate, accurate pressure readings across the 0–15 PSI range. The analog design eliminates electrical dependency and provides direct, tactile feedback without electronic processing lag—a proven advantage in high-vibration engine bays and during extended runtime diagnostics. The compact 3.9 x 1.9 x 5.9 inch footprint and lightweight 0.15 lb construction make it ideal for both permanent installations and temporary test setups on engine blocks, fuel rails, or carburetor inlet manifolds.

This gauge serves performance tuners, restoration specialists, and fuel system diagnosticians working on classic muscle cars, street rods, marine engines, and modern carbureted platforms. Technicians rely on this 0–15 PSI range to confirm fuel pump output before fuel filters and regulators, detect pressure drops indicating failing pumps or clogged lines, and validate carburetor float bowl pressure stability. Installation requires a tee fitting or existing fuel line access point; compatibility spans most naturally aspirated and supercharged gasoline engines where fuel pressure remains below 15 PSI.
