I have a 2017 Sundancer 400, and I am puzzled.
In the spring, I left the diesel tanks full, the electronic gauge indicated 98% each side, which is normal when I have full tanks. Whenever I fill up, I have my wife watch the gauge as I fill the starboard side, and to let me know when it reaches 98%, I stop pumping there, and move to the port side. Usually, it takes about the same amount of fuel in both tanks.
Since we got back down to Florida in Sep. we have made a few trips and put about 12 hours on each engine, and because it has been so hot, we have also put about 12 hours on the generator. Because the generator pulls from the starboard tank (according to the manual), I would have expected the starboard tank to be lower than the port. But when I headed out this morning, the gauges indicated that I had about 67% in both tanks. I was scratching my head about this, when it because more puzzling. I started to fill the starboard tank and my wife was calling out the percentage fill, but she also said the port tank was going up. My thought was that she was getting a false reading on the port tank due to weight distribution, but the starboard side took 65 gallons when it read 98%, and the port side read about 85%. I switched over it fill the port side and it took 10 gallons then overflowed.
Clearly, fuel is somehow transferring from one side to the other, and I don't understand how this can happen. I did not buy the fuel transfer pump, and I am pretty sure that this was not happening last year. Anyone know what is going on?

Climb down between the engines and look at the tanks and their connections. I also have an electric transfer pump but rarely use it. The tanks draw down pretty evenly even with the gen set drawing from the port tank ( gen set burns very little fuel. Less that 5 gals/hour.) Your owners manual should have a drawing on tank configuration. Good Luck!
