Replaced the power steering pump on my 72 "454" and the steering is difficult. Did the whole process per the service manual. Would air in the system be the cause of this problem? Any suggestions.

Define difficult for us....uniformly difficult, hard to turn wheel? Hard to turn one way but not the other? steering jumps to one side on startup etc etc..

Can you describe "difficult steering"....when you turn the wheel standing still at idle, does it feel like it is bouncing to the left and right? If so, you have air in the system....turn the wheel full left and let it sit overnight, that will get out any remaining air...
Replaced with rebuilt from local auto zone. At idle the steering wheel drifs to the left. When moveing steering seems ok to the left but hard to turn to the right. Will try the suggestion on turn to left and let sit overnight. Thanks all!
Replacing only the ps pump should not require adjusting the steering valve.
Personally, I would put the front end of the car up on jack stands and go thru the proper bleeding procedure of turning the steering wheel from lock to lock with the engine off.
I would agree that would seem to be the case, but his description of the problem does.
Bleeding is a must...but I don't think that air in the system would cause a drift while at idle...the only thing that could cause this in my opinion is the power steering control valve..and if it is the valve, then it must be way out of whack to be able to turn the wheels while the car is not moving.
There are plenty of threads about this. I don't think it's air and I'm not sure what is meant by bleeding; this isn't brakes. Check the fluid, it should not be foamy. If it is, let it settle so the air bubbles come out. Disconnect the steering cylinder from the frame. If the ram extends or retracts, the control valve must be balanced.

Jim, if you're reading this, that was a compliment. Everytime I sent a PM to Jim he responded promptly and was extremely knowledgeable. I even overpaid to get the GM power steering fluid (about $9 a quart) as recommended by Jim.

I recently installed a brand new GM ps control valve after dealing with a defective remanufactured valve for the past month. I also followed Jim's advice and went with GM ps fluid. The power steering now works perfectly.
