Robb, A lot depends on the type of pump, but the side to side type has been responsible for setting up an wave like motion that can rock the tender right off of the tracks! At least on some 3/4" scale engines I've seen. I imagine in one and one half inch scale, if you were sitting on the tender, to steady things, that wouldn't ever come into play! Another stlye I've seen which takes up very little room, was two cylinders mounted vertically! And a rocking lever between the two, so that when one cylinder was pumping, the other was on it's intake stroke! I don't think the orientation of the lever would matter a bit with this set up! As the bulk of the forces would be up and down, and not from side to side or fore and aft.
