It is actually a plug not a nut. You have to remove the plug and pour water into the dome to prime the pump. there has to be water in the pump before it will start working. Thanks for watching.
@Old-Engine-Dude the reason why I'm asking the bitumin sprayers I work on have the same plug so I'm assuming that cause these pumps work off the bases of water and you prime them with water the bitumin sprayers must need priming with bitumin before you start spraying how do you pour it in with a funel maybe?
I found a local water pump parts house but they didn't have the diameter I needed. I ended up going to a boot repair shop and they punched holes thru some thick leather and cut the diameter larger than I needed. Using a long bolt, a couple of washer, and a nut, I then spun it in a drill press and used an abrasive disk until I got a snug fit in the bore of the pump.
How powerful is the pump?
Do you know when it was made?
I don't know exactly, but I have seen them in F.E. Meyers catalogs from 1921-1941. Thanks for watching
@@Old-Engine-DudeI posted the history of the pump for you and your readers

Just curious where were you able to find the leathers for your restoration
