I am looking to add the Garmin GFS 10 fuel sensor to the boat. I only really need the sensor to show flow/efficiency of both motors together and not individually. Garmin recommends a separate sensor for each motor. Again, I am only looking for overall efficiency. To accomplish this I would need to mount the sensor inline above the spin on filters so it senses flow from the tank. The unit comes with it's own filter as well. Has anyone done this on their boat? Thoughts?
