1955 high pressure O ring?

[mogman]

I have a leak where the high pressure line leaves the pump and goes to the tee (three point) and power beyond. I seems obvious that it would be an O ring but I cannot find it in the parts book.
I do see an O ring 195278A, the comment is that it is not illustrated, would this be the O ring I need?

Call into Maibach parts on Monday, they're excellent.
