From earlier last year:
BB tank not sealed.
Doug Dino reposting long Diver mod thread - good info. In this case, a thicker 510 gasket created airflow issues for the v1 Diver - which led to tight draw and leaks. Sound familiar?
And one final bit from another Vapian post:
"Yet one more tip: Recently I started rolling up a bit of paper towel to about 4-5 mm in diameter and trimming it to fit in the Billet Box tank well, in the divot just behind the atty center pin. Just long enough to fill the gap in the back - NOT long enough to wrap forward around the atty of the carto (which would kill air flow ... but it might be something to try if you find the draw is "airy"). This ends up filling the air gap between the back compartment wall and the carto/Diver atty connector, and the bottom of the compartment and the tank. This serves a few purposes:
- As a diagnostic tool. If there's
juice in the well, this will help tell where it's coming from. If the bit of paper towel is soaked, juice is flooding from the atty connector; if it's dry or mostly so, it's most likely condensate from the top and might indicate the need to tighten down the brass ring a bit, or for a better-sealing drip tip. I think.
- Not entirely sure yet, but as a side effect it seems to sop things up when it's just a bit of condensate and keep the compartment drier. At least, it seems to me that the tank is coming out easier whenever I change tanks or replace the carto.
- In an emergency, you've got a tiny little paper towel with you. If you have to ask what that's good for, Richard Dean Anderson would like to have a word with you."
