Only lube is a light, oil nothing thick. Not a superman.Steve, you are superman if you can make a DRY pump pull oil. I too have primed an easy 100 oil pumps. I do them all the time on the stand as well. That's the only way to set max oil pressure. When I assemble the pumps I use a little assembly lube. That's it. I suggested the petroleum jelly only for this particular situation.
I would think running the pump dry would score the thrust. Metal parts need oil to prevent wear. I know you know that.
I watched RC run a completely dry pump with a drill on the bench when building it.
It certainly opened my eyes that day.
I know you have seen my videos of oil pump priming, no gasoline, no grease, no assy lube. I am doing one in a few I will video it again.
