You say "pumping oil", as opposed to "putting oil under pressure".
It would make a big difference it you comment on the pressure you
NEED and the flow in gpm that you want. Also, is the oil clean or not?
I don't think power steering pumps like dirty oil. Are you "building
up" several separate systems or do you want several pumps just to get to
some particular volume?
IIRC, many power steering pumps only deliver somewhere in the range
of 2-4 gpm, but at 1000 psi or more.

I want to build up several gear pumps for pumping oil. I figure that
getting steering pumps from an auto junk yard will be the cheapest route.

I wonder what vehicle may have the highest flow pump. Should I just
consider that the larger the vehicle, the faster the flow rate?
