So I'm borrowing a White Rhino which has one of those slim bottom coil tanks. It was working fine until I put some new juice in there and screwed it back together. Tried to take a hit and there was a weird gurgling sound. I unscrew it and see that the juice is actually coming out of the little hole on the bottom and leaking into where you screw it into the battery. ... why is this happening? I think I'm in trouble.
