reservoir does not have a return hose.? My van has been converted from left hand drive to right hand drive. The power steering reservoir is not attached to the pump it is located to the right and level with the top of the water coolant radiator. The reservoir only has one hose which is on the bottom of the reservoir leading to the top of the pump. The pump also has a high pressure hose and a smaller hose, both of which go to the steering box which is attached to the steering column.

Do I detach the smaller hose from the pump to allow the old fluid out? If so, do I have to block off one of the ends? If so which end? Do I stop fluid coming out of the pump or the steering box? Thank you.
