I have two hyper tanks and I am having the same issue with both. If I fill a tank within a few draws it will start to gurgle and I can take the tank off what ever unit I'm using at the time and the center post connection will be full of juice. I have tried new coils , dry burning ,everything I can think of but it still floods out. I saw a post somewhere that you can flip the rubber grommet over the coil and pack with cotton or something to that effect to stop it from flooding. But I didn't really get what the person was talking about. Does anyone else have this problem with these tanks? And does anyone know a solution.
