I would hook it up to the ps system, just for the purpose of keeping it lubed with ps fluid. I would be worried about it seizing up from letting it run dry.

 

Doesn't it operate by throttling the PS fluid from the pump? If the pump and/or the rack is not designed to handle that throttling, what will happen?

Probably need some advice from someone who understands how the speed-sensitive system works.

 

i guess ill hook it up to yhe ps to c wat happens from there
