The Garmin GFS 10 adds fuel consumption tracking to compatible Garmin chartplotters by transmitting flow data over Garmin CANet or NMEA 2000. Unlike many standalone flow sensors, it also reads fuel level when wired to an existing analog fuel gauge or resistive tank sender. Built specifically for gasoline carbureted engines without a fuel return line, it measures flow from 2 to 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 sender
• Compatible engine type: Gasoline carbureted engines only — not compatible with diesel engines or fuel-injected gas engines that have a fuel return line
• GPSMAP 4xx and 5xx series CANet-compatible units require a separate CANet kit to complete the connection
