There are several possible ways for all that to be hooked up
It could just be getting data from a sending unit in the tank. That data somehow gets put onto a
NMEA 2000 backbone. It's possible the
engine has it's own system and sends that data out to the 742
There could also be a flow
sensor. With one of those the 742 starts out with a certain amount of fuel and deducts what has been used
Look for something like this in the fuel line going to the engine:
