The Garmin GFS10 Fuel Sensor adds real-time fuel tracking to your Garmin chartplotter, helping you optimize your boat’s fuel economy with precise flow data. It communicates with your display over Garmin CANet or NMEA 2000, delivering fuel insights directly where you navigate.

A standout feature is its fuel level sensing capability. When connected to an existing analog fuel gauge or resistive tank sensor, the GFS10 provides fuel level information alongside flow data, giving you a complete picture of your on-board fuel status.

Features & Benefits

• Real-time fuel flow tracking up to 50 GPH per engine with a minimum detectable flow of 2 GPH.
• Dual data transmission via Garmin CANet or NMEA 2000 for seamless chartplotter integration.
• Fuel level sensing capability when connected to an analog gauge or resistive fuel tank sensor.
• Robust construction with 3/8" barbed fittings for secure plumbing.
• Low back pressure design: 0.5 PSI at 20 GPH and 1.0 PSI at 40 GPH.
• Wide operating voltage range: 10–22 V for reliable marine use.
• Fire resistant and USCG compliant, designed for safe, tough marine environments.
• Important compatibility note: GPSMAP 4xx and 5xx series CANet-compatible units require a CANet kit for full connection.
• Important limitation: Not compatible with diesel engines.
