Bleeding Federal Power Steering pump

In the middle of the 4th pic I posted shows the relief valve and how it goes together. If the spools and/or spring is put in the wrong location it will not make any pressure or can overpressurize. If you did not remove these parts you should be fine providing the pump was working to begin with. If you did remove them i would suggest you check and make sure they are installed correctly. Its been a while since I have looked at a federal pump but typically the nut that holds the reservoir on in the rear is part of the relief valve. This is the part the hose screws into.
If you did the repair on the car it is very possible for a part to fall out any you may not have noticed it.
