1-1/2 Fuel Pressure Gauge 0-30psi

The 1-1/2 Fuel Pressure Gauge 0-30psi from Advanced Engine Design is an essential diagnostic and tuning instrument for fuel system troubleshooting and engine performance monitoring. Designed for mechanics, technicians, and enthusiasts who need reliable pressure readings during carburetor work, fuel pump diagnostics, or post-modification verification, this mechanical analog gauge delivers the accuracy required to confirm proper fuel delivery under varying load conditions. Whether you're diagnosing a weak fuel pump, verifying a newly installed fuel regulator, or validating changes after an engine build, this 0-30 psi range covers standard naturally aspirated and mildly boosted applications.

This 1-1/2 inch diameter fuel pressure gauge features a white face dial with clear black graduations for quick, accurate readings even in shadowed engine bays. The mechanical construction eliminates electronic drift and sensor failure common in digital displays, making it ideal for temporary or permanent installation on test benches and vehicles alike. A 1/8 inch NPT port thread allows direct connection to standard fuel line adapters and test manifolds, ensuring compatibility with most fuel system configurations. The analog movement responds instantly to pressure fluctuations, enabling technicians to detect pump flutter, regulator creep, or injector back-pressure issues that might otherwise go unnoticed.

This gauge excels in both shop and field settings—mount it inline during fuel system troubleshooting, attach it to a fuel pressure test kit for baseline measurements, or install it permanently on carbureted or early EFI vehicles where factory gauges are absent or unreliable. The compact 3.8 x 1.95 x 4.45 inch footprint fits easily under hoods and in engine compartments without interfering with hoses or components. Its robust mechanical design tolerates vibration and temperature swings common in modified engines, while the straightforward NPT connection simplifies installation on vehicles with stock or aftermarket fuel rails. Mechanics building carburetors, upgrading fuel delivery systems, or diagnosing drivability complaints will find this gauge an indispensable reference tool for confirming system health.
