Since I was curious I looked it up. The secondary tank periodically transfers fuel to the main tank. No action needed on your part.

This is not an answer but a question. My 2016 3500 has duel tanks. My gauge says empty but my front tank is full, the back tank was empty but when I filled the back tank up (the front was full) it says I have a half a tank.grrr please help I am very new to this and yes I read the manual... all 3 as a matter of fact and I googled it.
