Hello All

I finally broke down and bought a re-manuf power steering pump for my 85' RX7. THe problem that I have - it still whines.! I have bled the air from the lines, and the power steering works...........the only thing that I can think of, is the where the power pressure switch is, that fitting was installed 90 degrees of where it needed to be. I loosened and turned it 90 so that I could install it. Does that have to be exact? Or do I have a bad pump??? Any hints???
