Thanks... yeh, I do that.. works like getting it out of a syringe but my bubble trouble (LOL) is when filling the tank with the atty hole side up. There's juice at the hole that keeps the tank air from coming out unless I just keep filling and let the air push that juice out. I not only loose juice that way but its a mess. The tank that leaked had alot of that air and a lot of juice at the hole so I just didn't fill it all the way if I remember correctly. I've tried everything to get that juice at the hole out before trying to fill but, so far, the only thing that half-way works is sucking it up with a syringe. So, I think too much air in the tank filling caused some sort of pressure problem and caused the leak just sitting in the PCC. I have tried the flicking thing before trying to fill but it doesn't work. I think maybe because there's not enough juice at the hole for the weight of it to jar loose and run down into the tank so the air can come out. I don't know if this is what causes leaks until or unless there's a repeat of what happened. But I would sure like to know how to get that little bit (sometimes more or less) away from the atty hole so the air can get out.
Edit: Its wordy but was hard to explain. Anyway, most times I don't have this trouble and fill right up to the top and haven't had leaks so I think this must be, at least partly, what the cause of some leakage is.
