In-Line Fuel Press Gauge

The In-Line Fuel Press Gauge by Mr. Gasket is a mechanical fuel pressure monitoring instrument designed for automotive enthusiasts, mechanics, and performance builders who require real-time diagnostics of their fuel systems. This analog gauge provides critical visibility into fuel delivery pressure, helping to identify carburetor tuning issues, fuel pump performance degradation, or regulator problems before they compromise engine operation.

This full-sweep mechanical gauge measures fuel pressure in a range of 0–15 psi and features a 1-1/2 inch white-faced dial with clear, easy-to-read markings, making it suitable for use in engine compartments and workshop settings. The instrument connects via a 1/8 inch NPT port using the included adapter fitting, allowing for flexible installation directly into fuel lines or filter housings without permanent modifications. The analog needle response is immediate and unaffected by electrical interference, ensuring reliability in environments where digital gauges might falter.

Built to Mr. Gasket standards, the gauge withstands vibration, temperature fluctuations, and the corrosive fuel environment. This tool is ideal for carburetor-equipped vehicles, classic car restoration, street rods, and any application requiring fuel pressure verification without computer diagnostics. The 0–15 psi range is compatible with most naturally aspirated carbureted and low-boost fuel systems, making it a versatile addition to any automotive toolkit.
