your Garmin requires nothing more than the NMEA 2000 input from the yamaha -

(why Navico requires (continues to?) a separate module is beyond me)

Using the Garmin "virtual" fuel gauge - "Total Fuel Onboard"-
rather than an actual N2K fuel tank level sensor input (which is an alternative)

you will at any time have three options:

I use the Garmin function, and find the Yamaha input very accurate.

However, I would not be comfortable without a "second opinion";
I also have a WEMA tank sender and analog VDO gauge -
which, motionless at the dock, is repeatable/accurate/precise to well within 5 gallons
