if you got a diff rad with no rad cap and just a bleeder nipple on it, you could run a much simplier setup

like VW's run, expansion tank simply has the bottom outlet going to a rad hose, while the upper one goes to the nipple on the rad, it constantly flows coolant/air bubbles through the top and out the bottom of the tank


or you could keep your stock rad and have a very small expansion tank like the ones shown and run 4 hoses all over the place.
