yep stock everything, really confused how it happened...
the orings are just a little bit stretched, they seem to be otherwise fine and still functional!
i have a new problem now though, i had to disassemble the tube holder section to remove and fix the screen over the heater, and now im not sure how to put it back together properly... i have this big red oring that i thought went under the tube holder that screws in, but it doesnt seem to have a good place except in the threads the holder screws in to, and if i screw it at all tight the oring gets squashed out into the tube area blocking my glass stem from going in! i wish tm had picture instructions for dissasembly and reassembly, especially since this seems to be a pretty common problem
edit: turns out it is in the instructions, guess youre just meant to only partly screw the tube holder lid in?
