As a test I'm gonna pull the roll over valve to
see if thats the restriction in the vent... thats
sorta the way it acted.. it was after the full on
boggy which might have had a vac in the tank.. its
worth a check... I have a #an8 vent... if that is
the issue.. I will add a side to side line with a
drop below the tank so it would be above the tank IF
I were upside down... the side to side has to go past
the sides of the tank so they would be higher than the
tank if its on its side
