Sounds like my previous gibberish was a little confusing, which often happens! lol

Let me clarify, prior to my repairing it:
there was no gasket where number 27 is shown. And the gasket shown by 27 in that diagram was found where 29 is.

I have since installed new parts exactly as shown in that pic.
