I went to the site where you bought the stuff, they had a good tech on how to mount the pump but all else is vague. The drag link from pitman arm to the steering arn on the spindle has to be deadnuts level at ride height and as long as possible.
can you show us a picture of what your looks like? That site didn't provide a picture 'as assembled'.
If the draglink is running up or downhill you might be albe to correct by bending the steering arm or making some spacers, need more info.
