1-1/2in Pressure Gauge - 0-100psi - Black Face

The 1-1/2in Pressure Gauge - 0-100psi - Black Face by AutoMeter is an essential mechanical instrument for any serious automotive enthusiast or mechanic diagnosing fuel system, oil pressure, or custom hydraulic circuits. Whether you're tuning a modified engine, troubleshooting a fuel injection system, or monitoring aftermarket boost controllers, this analog pressure gauge delivers reliable real-time readings in the critical 0–100 psi range. The 1-1/2 inch diameter face offers excellent visibility in tight engine bays or on custom fabricated gauge panels, making it a trusted choice for street rods, performance builds, and shop diagnostic stations.

Built as a liquid-filled mechanical gauge, this AutoMeter unit features a sealed, dampened movement that resists vibration and needle flutter—critical when mounted in high-vibration engine compartments or on competition vehicles. The black dial face with white numerals and markings ensures legibility under both daylight and night conditions, while the 1/8 inch NPT port accepts standard automotive fittings and aftermarket braided stainless steel pressure lines. The robust all-metal construction and internally-damped Bourdon tube design eliminate the erratic readings common to cheaper dry gauges, providing the consistent accuracy that serious builders and mechanics demand during baseline testing, tuning sessions, and ongoing vehicle diagnostics.

This gauge suits fuel pressure verification on carbureted or EFI engines, oil pressure monitoring on high-performance builds, transmission line pressure observation, and custom hydraulic or pneumatic system measurement. Installation requires only a 1/8 NPT adapter and appropriate gauge line—no electrical wiring or calibration needed. Its compact footprint (1.9 x 7.75 inches) fits dash pods, A-pillar mounts, and custom gauge brackets, making it ideal for restorations, track cars, and shop benches where reliability and accuracy directly impact tuning decisions and component longevity.
