I'd suggest taking off the front access plate, and having a look at the dippers and connecting rods. You'll want the oil level to be JUST below the crankshaft/connecting rods. My 30/2 has a bolt at the top of the access plate, pointed downward. I take the bolt out, and shove a brazing rod down into the hole to measure oil level. For me, and my 30/2, that's 1.75 inches.
No idea about the pump, but if you're needing a spare, you might contact DES.
