When I get mine really full it seem to leak near the inlet valve for quite a long time but eventually quits. I too think, at least on mine it'sthe overflow tube. If yours keeps leaking until the tank is empty you may have a problem. If it stops after a couple of gallons areused out of the tank maybe a lose hose connection or overflow tube working correctly.
