The Garmin GFS10 Fuel Sensor adds real-time fuel tracking to your Garmin chartplotter, helping you optimize fuel economy with precise flow data. Built for serious boaters, it delivers fuel insights exactly where you navigate and can also report fuel level when paired with an analog gauge or resistive tank sensor.
-
Real-time fuel flow: Tracks up to 50 GPH per engine with a minimum detectable flow of 2 GPH.
-
Dual data transmission: Connects via Garmin CANet or NMEA 2000 for seamless chartplotter integration.
-
Fuel level sensing: Provides fuel level information when connected to an analog gauge or resistive fuel tank sensor.
-
Robust plumbing: Built with 3/8" barbed fittings for secure, leak-resistant installation.
-
Low back pressure: 0.5 PSI at 20 GPH and 1.0 PSI at 40 GPH to minimize impact on fuel flow.
-
Wide voltage range: Operates reliably on 10–22 V for marine environments.
-
Safety and compliance: Fire resistant and USCG compliant for use in tough marine conditions.
-
Installation note: GPSMAP 4xx and 5xx CANet-compatible units require a CANet kit to complete the connection.
-
Engine compatibility: Not compatible with diesel engines.
With the GFS10, you gain a complete view of your fuel status in real time. The combination of accurate fuel flow data and optional fuel level sensing helps you plan trips, optimize engine usage, and monitor consumption more effectively. Its dual CANet/NMEA 2000 connectivity ensures you see fuel insights exactly where you navigate, while the rugged, marine-grade construction supports reliable operation in variable conditions.
