First off hello MCB people.
I'm working on getting my Lvl 7 68 classic up and running and I'm in the process of rebuilding my flatline 3k. I got a kit from AGD and it only had 6 of the 7 o-rings, it was missing one of the smaller o-rings. AGD sent me 1 of each of the smaller o-rings, very nice of them. My question is this, is the check valve o-ring the smallest in the kit and then the seat and the on/off o-rings are the same size or do I have this wrong?
Also I was following the rebuild guide HERE
and he fails to mention the size of the on/off and the size of the check valve.
