I’m searching for the other side of the manifold, so I can add a sight glass to the other side of the pump.

I had the same issue with a tokheim tall 39. I had a square plug in the main sight glass assembly and was missing the other end. Tom Buckles had what I needed so you might want to check with him to see what's available. He lists a lot of parts on his web site. Bob

Thanks. What is his website?

Call him or PM him on here. Just because a part isn’t on his website, doesn’t mean he doesn’t have it.

Thanks
