Was the missing oring the one on top of the plastic tank? Mine is leaking and I am thinking I need to take it apart tonight.Got the Cabeo up and running, had to watch a video to see how it all comes apart and back together again, glad I did, as had a oring missing on mine, so got a spare out of the bag and running good. Didn't like they sent a silver ring to use your own drip tip, why it would be silver for a complete black tank, but got the spray paint out and it is black now
