1-1/2 Fuel Pressure Gauge 0-15psi

The 1-1/2 Fuel Pressure Gauge 0-15psi by Advanced Engine Design is an essential diagnostic and monitoring tool for carburetor-fed engines, low-pressure fuel systems, and mechanical fuel pump applications. Whether you're tuning a vintage hot rod, troubleshooting fuel delivery on a classic car, or verifying proper pressure during carb work, this mechanical analog gauge delivers real-time insight into your fuel system's performance. Mounted directly to your fuel line or fuel rail, it eliminates guesswork and helps prevent lean-out conditions, vapor lock, and fuel starvation issues that plague carbureted and early fuel-injection platforms.

This gauge features a robust 1-1/2 inch diameter face with a crisp white dial and 0–15 psi range—ideal for gravity-feed, mechanical pump, and low-pressure EFI circuits where high-pressure readings are unnecessary. The 1/8 inch NPT port threads directly into fuel blocks, regulators, or custom manifolds without adapters in most cases, while the mechanical needle design requires no power source and remains immune to electrical gremlins. Built by Advanced Engine Design (MPN 6100), this compact, lightweight instrument (0.14 lbs) tolerates fuel fumes and temperature swings common in engine bays and won't fail due to corroded wiring or a dead battery.

Mechanics, hot rodders, and fuel system specialists rely on this gauge when diagnosing low-fuel-pressure complaints, verifying regulator settings, or commissioning custom carb conversions. Its 4.6 x 1.8 x 6 inch profile fits snugly in tight engine compartments and mounts easily to dash panels, firewall brackets, or inline fuel system housings using the standard NPT connection. Pair it with quality stainless steel fuel line and a fuel block assembly for a professional-grade pressure monitoring station that will serve you across multiple projects and platforms.
