Ok, so I received my Nautilus v2 today and of course there are problems, I think. Ordered a small mouthpiece that said it was for the Nautilus but it will not allow me to put the top cap on with one tank...
This is the more pressing concern for me at the moment. My center post assembly housing thingy seems to be missing an insulator. I have tried to set this thing up twice but as soon as I fire the button on my EA mod the button starts getting extremely hot and my guess is that it's shorting out because it is missing that insulator and is metal on metal. Is that right? Here are my pics and a screenshot I took from a tutorial video of the Nautilus v2
Of course I don't have any extra o-rings to put there either

Is that supposed to be some hard plastic delrin piece or is it a small o-ring?
I was so stoked to use this thing, now I'm totally deflated
