Garmin GFS 10 — Marine Fuel Flow Sensor
The GFS 10 is an inline fuel flow sensor that connects to your NMEA 2000 network and feeds real-time fuel consumption data directly to compatible Garmin chartplotters. Once installed, your display shows live fuel flow rate, fuel economy, and estimated range-to-empty — giving you the information you need to manage fuel on extended passages and avoid running dry.
It works with both gasoline and diesel engines and handles flow rates up to 378 litres per hour (100 GPH), covering the full range from small outboards to large inboard engines. For twin-engine vessels, one sensor is required per engine.

Parts Desk Insights
Best Use Case: The GFS 10 is the right choice for boaters who want accurate, real-time fuel management data on their Garmin chartplotter without installing a separate fuel management system. It’s particularly valuable on larger vessels, offshore fishing boats, and cruisers where fuel planning is critical and the cost of running low is high. The range-to-empty readout is especially useful when running at varying throttle settings across a long passage. For twin-engine boats, you’ll need two sensors — one per engine — and your chartplotter must support dual fuel sensor input. Confirm your Garmin chartplotter model supports NMEA 2000 fuel sensor data before ordering.
Installation Note: The GFS 10 installs inline in the fuel supply line between the fuel tank and the engine. Ensure the sensor is oriented correctly per the installation guide — reverse installation will give inaccurate readings. Use fuel-rated hose and clamps at all connections.
Estimated Packaging: Box approximately 8" × 6" × 4" (20 × 15 × 10 cm), approx. 0.4 kg shipped.
