Does anybody have a schematic or listing of the oring size or sizes (I suspect they are viton orings) in the female gas line (tank to motor) fitting that hooks on to the early 70s motors?

The outer one appears to be a 204 or a 205 size oring but the one I have measures just about right smack dab in the middle of the two.

I would suspect that the old one I have might be the 205 and has been compressed over time and just measures a bit smaller but if anyone knows for sure, I'd like to know for sure too.
