Beautiful engine. Mine needed a few parts and the valves were stuck.
I worked the problems out and it runs well. I do need a pulley for
the inside end of the crank/drive shaft.
Re the pump...I too have issues. If I rotate the flywheel by hand
when there is no pressure in an empty boiler, the pump has worked,
sending water up. With a steamed up boiler, no go.
By-the-by...My Empire B43 pump has two ball-bearing check valves.
Hmmmmm,

Does the engine stall, or deadhead? Or does water just squirt out onto the eccentric, when the boiler is steamed?
