i am replacing the power steering pump. When I took off the pressure hose the nut was tight in the pump but the hose was still loose and it was leaking. When I tried to put the hose back into the new pump it is still loose after the fitting is tight. I am not sure if this is how it is supposed to be or not. Is the metal part supposed to be able to swivel in the fitting once the fitting is tight or not. If not what is wrong. Do I need the O ring that came with the new pump? The dealer said no. I know I need the Teflon ring and I used that. Please help I don’t want to spend $60 on the hose if it is not needed.
