power steering question

Hi got a 2007 chevy aveo 5 door the power steering steel pipes down on the rack there is 2 of them aprox 5/16 dia well one of them has sprung a leak and other wont be far behind . would these be the same material as brake pipes and what would the fittings be. would they be bubble flair or inverted flair like brake pipes . as i dont seem to be able to find them as parts all the searches i have done seem to have them all ready attached to the steering rack . it was not my intention to replace the rack just because the pipe has a hole in it .
has anyone been there that could give a little advice please thanks mike
