OK, a little bit of digging revealed the following. I think in 1992, the routing of the high pressure line was changed, requiring a longer length. 1990 and 1991, the line comes from the output of the pump, and runs down, then towards the front cover of the motor, and the balancer. it then curves back towards the steering rack.
I think the 1992 - 1995 high pressure hose, comes out of the pump, then runs down and outboard towards the frame rail, perhaps, and then comes back inboard towards the rack.
It would be great if someone can confirm the routing in their 92-95.
