I am replacing my power steering box. I got the same box (7802644). The new box had a yellow "insert" in the high-pressure inlet which I stupidly thought that was just a plug, so I pulled out. When I tried to connect the existing high-pressure hose it will not thread in. Now I am thinking that yellow thing needs to be in there. When I look for a new hose they all seem to provide that yellow thing. what is up with that???
