Still having problems with the go-tanks. I don't know what I'm doing to them but they always end up leaking after 2-3 fills. It really sucks because I absolutely love them, and am really beginning to hate carts.
Hi stomkat... Sorry to hear you're having some problems with the Go-Carts.... I'm going to do my best to help you out a little bit here, but I may have to ask lots of questions so that I can be perfectly clear that we're both on the same page... K?
At some point the rubber inside stops sealing at the mouthpiece.
I just want to state upfront, in case you don't already know... the Go-Carts don't 'slide' into the mouthpiece, but 'screw' into them. Are you certain that you're getting them screwed on securely? Also, when you go to refill them, are you being 'careful' not to get any Nicotine Liquid in the 'center tubing?'. Please don't get angry at me if I sound 'redundant' to you or am asking the obvious... again, just want to make certain we're on the same page so that I can help you... if I can. I don't work for CigEasy or Frank.... I'm just very familiar with their products. I had previously raised the rubber to get the contact back, and it's still leaking.
OK I noticed that the clear 'tube' has been coming loose from the bottom, so I started pressing it back down. That usually solves it for 1 fill, then I once again have a leaking tank.
Is it at all possible when you went to 'raise' the rubber seal at the mouthpiece you may have inadvertently lifted the tubing? I'm not saying that's what you did, I'm just asking if it's a possibility?
I've tried completely disassembling it, cleaning it well, putting it back together, that works for one fill if I'm lucky then it's leaking.
Really?!? 
You disassembled & reassembled a Go-Tank & it worked with no leaks for up to ONE fill?!? The center tube is crooked in a couple, can't seem to resolve that.
I'm perplexed by this one 
I'm sitting here staring at 5 tanks that I refuse to throw away, but don't know how to fix either.
I was thinking if there was a rubber washer at the bottom of the clear tube it would help, but that would cause the rubber piece on the center tube to not be able to seal with the mouth piece.
hunh? 
I seem to be the only one having all these problems with them cause everyone else is saying they can use them for months, mine are broke within 2-3 days. What am I doing wrong?
