Power steering pump question...

[bigdon-70blazer]

I replaced the 1970 Blazers power steering pump last year around May and drove it around last summer. I had a little issue that the pump fluid sort of boiled or foamed itself out the top cap hole while I was getting the bugs first worked out and I figured that was normal and the problem went away for the balance of last year. Fast forward to this year when I drive it about 10 miles away for some touch up paint and shake down after winter storage. Foaming out cap returns now with vengence. The pump sounde horrible and I decided that I was going to replace it with another pump from auto zone because it has never been completely quiet since installation when I replaced the original one. My question is this, it seems that to get the hoses to go thru the brackets, they seem real tight and tightly cornered to get them to go thru there. the metal tube on the back of the pump, the return hose side seems to be bent from the factory in such a way that I have no choice but to go thru the bracket and I am asking because it may have too much of a bend that it it impeding the flow and causing this foaming action. Anybody seen this? I showed the guys at O'Reillys and they were baffled and replaced my pump. I asked them if I could bend the metal tube around a little so that the angle would allow a more easy bend in this area. They said that is the way it is supposed to be. I do believe I had the sides hooked up correctly. Help. Any pics of how yourcame out would be great, especially original application!
