Gary, Not sure you are aware, but if you are running the wing tanks dry, and using some from the main, when you fill up you need to fill the main tank, let the fuel flow back to the wings thru the overflow. (when the main cork quits going down)

In any event, the tanks slowly level out when being filled. Like I said, what do I know.
