Garmin GFS™ 10 Fuel Sensor for Gas Engines Only

The Garmin GFS 10 Fuel Sensor is a precision instrument designed to bring real-time fuel consumption monitoring to your vessel's Garmin chartplotter system. Built specifically for gas engines, this fuel flow sensor eliminates guesswork when managing your boat's fuel economy during long days on the water, whether you're running a weekend fishing trip or extended offshore operations.

The GFS 10 integrates seamlessly with Garmin CANet and NMEA 2000 networks, transmitting live fuel flow data directly to your chartplotter display. A standout feature is its dual-capability design: beyond tracking fuel consumption rates, it also provides fuel level sensing when connected to an existing analog fuel gauge or resistive fuel tank sensor. The 50-gallon-per-hour maximum flow rate accommodates most recreational and commercial gas-powered vessels. Integration with your chartplotter enables precise fuel efficiency calculations, helping you optimize cruising speed and route planning to maximize range and minimize operating costs.

Anglers and cruising boaters benefit most from this system. Tournament fishermen can monitor fuel burn rates across different throttle settings to dial in efficient cruise speeds. Offshore operators gain visibility into fuel consumption trends, enabling better trip planning and cost management. Coastal and lake boaters appreciate the simplified fuel management without adding redundant gauges to the helm. Installation requires integration with your Garmin network—compatibility with your specific chartplotter model should be verified before purchase.

Garmin's fuel monitoring ecosystem represents a practical step forward for modern vessel operators who want data-driven insights into engine performance and fuel efficiency. The GFS 10 pairs well with other Garmin marine electronics, creating a comprehensive onboard monitoring network that supports better operational decisions on the water.
