Default Managing fuel quantity?

So, am getting new boat with 250 Yamaha, but without Yamah gauges ...clean console except for switches and CB panel.

Looks like straightforward install of 8xx Garmin MFD, but I hadn't even considered how to monitor total fuel in the tank ...looks like the broad process of knowing how much fuel in the tank relates to a full starting point, resetting the fuel management software on the MFD each time you refuel to Full, then the MFD takes burn rate from the motor (with time factor), and subtracts that number from the total fuel added (based on number of gallons setting you put into the MFD for "Full."

Some folks report they added a Lowrance (Navico) Fuel Data Manager as an interface - Simrad shows the same part ...looks like a common part. This device apparently stores the burn rates and maintains the data all th tim, whereas some MFDs will only compute but not store the data?

Is this needed in all setups, or just certain MFDs?

Here's what Navico says about the device:

"Navico Fuel Data Manager

Monitors Fuel Rate/Fuel Flow from NMEA 2000 engines, and accumulates Fuel Rate into Fuel Used. Outputs seasonal, trip and total fuel used.

Features
Replaces EP-85
Monitors Fuel Rate/Fuel Flow from NMEA 2000 engines, and accumulates Fuel Rate into Fuel Used
Outputs: Seasonal/Trip/Total Fuel Used
Will report accurate Vessel Fuel Remaining if MFD Fuel screen is maintained at every refuel
One sensor will monitor up to 3 engines
Additional Fuel Data Managers can be added for more engines
Will monitor fuel rates from multiple engines transmitting through a single gateway

Manufacturer Part Number: 000-11522-001
