Can someone explain to me how the Yamaha engine gauge gets its fuel quantity reading? I still have dealer loaded fuel on board and would like to know if its a float type sensor or if the dealer had to program something into the gauge to make the readings accurate. I am just trying to figure out if I could trust whats on the boat now or I need to fill it up and program some information into the gauge to get more accurate readings. Thanks!
