PS hose connections

Hello:
I have converted to power steering and Hydroboost as part of my 67 LS swap but I am having hard time to bleed the PS pump. It keep humming and the fluid foams (cavitating, I guess). It is a new (rebuild) ACDelco pump. I am wondering if I have connected the return lines incorrect, if that matters. The pump has two return lines and one high pressure line, one return line sits higher than the other. Can anybody tell me the return line from steering box connects to the lower return line or the upper?
