Experienced mechanics come in....
I just replaced my power steering pump on mine last weekend.
Did you replace the little o-ring on the pressure hose too?
I installed mine with a little bit of Vasaline (trick I learned rebuilding the 727 tranny in my 'Cuda)
Check to see if the hose isn't loose, or if you didn't over tighten it and ruin the o-ring.
Just throwing things out there. Hope you figure it out.
