Yeh I know what you mean, every single tank of mine leaks somewhat. I've just got used to having to wipe my mods down when I change tanks. Usually I get juice sat at the bottom of the tanks.maybe i'm biased because atm my daily is the tfv8 with 22/32 fused claptons which you can either leak occasionally or get dry hits constantly, its so bad atm i literally have to take the tank off the mod and hold it in towels whilst it fills and leaks up enough to get a vacumn going
But at least it's not like Niagara Falls lol.
