Why the check valve Brian?Dave

I don't think this gear pump will create enough suction to start dry and pull oil or water up from a sump to "catch" and my thinking is that if it has a check valve in it the pump won't have to be primed every time it is ran. It doesn't cost anything to put a check valve in it, and imagine how awful it would be if someone built it to use as an oil pump for an engine and didn't prime it. They wouldn't know it wasn't working until something burned up.
