Garmin GFS 10 Fuel sensor
Add fuel tracking capabilities to your Garmin chartplotter and optimize your boat's fuel economy. The GFS 10 tracks fuel flow use and sends the data to your chartplotter via the Garmin CANet® or NMEA 2000®.
Unlike other fuel flow sensors, the GFS 10 will include fuel level sensing capability when connected to an existing analog fuel gauge or resistive fuel tank sensor. Maximum fuel flow rate for the GFS 10 is 50 gal/hr (189.27 L/hr), and the minimum flow rate is 2 gal/hr (7.57 L/hr).
Note - does not work with diesel engines.
