"c. The hole in the top is 4 3/8" in diameter. What holds the globe to the top?"
I purchased the aluminum 541 globe adapter from gaspumpheaven.com, which I think comes blank (no hole pattern). Had to drill both the adapter and the pump top to match. Think I also tapped the adapter and attached it with machine screws from under (inside) the top. You could also just use countersunk sheet metal screws from the top.
