There is one outlet on the factory housing, so I can't use a return setup if I put a pump in the stock location unless the return is plumbed to the bottom of the tank. I see what you mean about resistance though, might create some back pressure in the return line. When this is all done I will definitely verify pressure with a gauge.

The upper part of the tank is wedged into the frame so only the bottom area is accessible. Maybe I could sump for the feed and put the return into the stock line on the top. I'll have a better idea what is possible once I drop the tank. Thanks for the input so far.
