It`s not as dramatic as the images I put up previously !
It`s quite easy, just like any other similar tank assembly
1. Unscrew the 510 pin
2. Remove the 510 insulator
3. Unscrew the diffuser
4. Using a small flat-head screwdriver - unscrew the airtube from inside the 510 (it is slotted)
5. The positive post and insulator will come free - allowing access to that tube as seen above.
It`s how they assemble them, so a simple reverse - nothing forced, nothing de-press-fitted
Of course, this is still just theorising on my part - hence why I am giving this final test a few days to yield any results -
one way or the other.
To recap: I think liquid could be getting under the positive hard plastic insulator (over time) and down eventually into the base, finally making it`s way out of the AFC ring and onto some people`s fingers.
NB:
Unless the diffuser is acting like a capillary sponge due to the design and
actively drawing liquid in - this is another possibility of course.
That would tend to make you think it would happen all of the time, it doesn`t - so it`s all a bit of a mystery.

Having thought about it some more, I suppose another simple test would be to run the tanks without the diffuser - but with the new o-ring still in place.
That would rule out the diffuser itself being instrumental in any seepage.
It would take days (weeks !) trying to test this properly with different wicks and juice viscosities and vaping styles ad nauseam - I`m not prepared to do that !
...but if a simple fix can be found to help things along, then it`s worth a couple of days of fiddling.
