Rich,
Take a strong flashlight and shine it on the left side of the engine in a plane with the engine valve cover. Slightly to the left of the valve cover all the way forward to the engine bulkhead is the other pump. I think you have a C-12 Cat, so it may be in a different location. You can also lay on your back under the coach. On the rear driver's side, shine your light up between the radiator shroud and left side of the transmission at the rear engine bulkhead. If you were to remove your engine access cover inside(not easy of course) and looked under the access hole, driver's side, you should see it. Try again from the outside with the flashlight shining all the way to the left front from the rear engine access.
