The LONGACRE Waterproof SMI Fuel Pressure Gauge (0–15 PSI) is a precision electric fuel pressure monitoring instrument designed for marine engines that require reliable and accurate fuel system diagnostics. This gauge is particularly useful for offshore anglers, commercial fishermen, and recreational boaters who operate in demanding marine conditions.
Built with stepper motor technology and a fully sealed waterproof SMI Elite housing, this analog gauge provides consistent performance in environments where standard mechanical gauges may fail. The 2-5/8-inch black-faced dial displays fuel pressure across a 0–15 PSI range, offering instantaneous feedback on fuel pump health and injector system integrity.
The 0–15 PSI range is suitable for most gasoline-engine applications, including four-strokes and smaller displacement outboards. This compact gauge fits standard marine instrument panels without significant modification, making it an essential tool for monitoring fuel pressure in various marine applications.
