To do it on low flow i would have to get fitting to reduce it down form the large couplers the small couplers to work.
Do it at an idle, its not going to provide 30gpm at an idle. Use a 55gal drum, if you want you could also fab up a quick assembly to screw into the bung hole and your return and case drain can both go into that manifold. BTW we use black steel pipe.
