I experienced the very same thing years ago. When my three tanks were full or nearly so, the rate of fill into the center tank was greater than the rate of fuel burn plus the rate at which the excess fuel returned to the wings. The result was that a column of fuel would climb the glass tube and sometimes it would come out the vent and get on my windshield. This was a long time ago but I believe my memory is accurate when I tell you that we changed the size of the orifice (restriction) in the fuel pump fitting (or line) to a slightly smaller one so that the rate of fill of the center tank by the fuel pump from the wing tanks was slowed just enough that this overflow condition would not occur; the over fill or overflow condition that is evidenced by fuel climbing up into the fuel gauge sight glass and occasional overflow from the center tank cap vent. Now, this problem may subside when your fuel level burns down somewhat and your tanks are not absolutely full. Burn out half your fuel and watch it to see if it still does it.
