I'm looking at a MOPAR small block fuel pump and have no idea which is the inlet and which is the outlet. The engine is not in a car. Nothing is marked

This may be obvious to many of you, but I'm clueless here.

Put your finger over the orifices and see which one sucks. I would assume the nipple is the inlet, the threaded end pressure out.
You can never have too much power, just not enough traction...
