The Garmin GFS 10 Fuel Sensor adds fuel tracking to compatible Garmin chartplotters, transmitting flow data over Garmin CANet or NMEA 2000. When wired to an existing analog fuel gauge or resistive tank sender, the GFS 10 also captures fuel level readings — a capability not found on many competing flow sensors. Designed for gasoline carbureted engines without a fuel return line, with a flow range of 2–50 gallons per hour.

Specifications:

• Compatible networks: Garmin CANet, NMEA 2000
• Maximum fuel flow rate: 50 gallons per hour
• Minimum fuel flow rate: 2 gallons per hour
• Fuel level sensing: Yes, when connected to an existing analog fuel gauge or resistive fuel tank sensor
• Compatible engine type: Gasoline carbureted engines only (does not work with diesel engines or fuel-injected gas engines with a fuel return line)
• GPSMAP 4xx and 5xx series CANet compatible units require a separate CANet kit to complete the connection
