By chance did you see what kind of pressure you are getting at remote valve in the back of tractor? I make up a gauge with a gauge from an Oxygen regulator, 1/4 inch coupling, 1/4x6 inch long nipple, 1/4x1/2 inch reducing bushing, and Pioneer Male end. Check to see the pressure and if the needle jumps around on the way up. I usually set the pump with the valve on the pump to 2000 lbs. or a little more.
It does sound like air in the suction end. Did you change filter? If so make sure it seated right and it is tightened up pretty good.
I have a 2255 and will check in the morning to try to see where it could suck air and post back.
I have never had that problem changing pumps, but there is always a first time for everything.
By the way is the steering jumpy? Also, is it a steel or aluminum pump?
