Since you've got an 87 did you use all the original (stock) pump ect, or did you switch things out to use the factory hydro parts? If you're still using the 86-87 tank then there's other problems. The 83-85 use the pump as the tank.

If you have a reman power steering pump, I bet it is turning backwards. IIRC non turbo cars have the power steering pump which flows the other direction. From personal experience. This is why I buy new.
