How the hell do I get the high-pressure steering rack hose off?
 

The one with metal inside of it?

Here's a picture:

I just completely removed everything having to do with power steering (Pump, reservoir, lines, those things) and I was going to finish up by looping the steering rack lines and that just has to fuck me in the face now.

And on a side note, how much does a full PS system go for?

unscrew it

So it's permanantly connected besides that? In that case I'm going to cut it a couple inches in front of where it screws in and just loop it that way.

17mm wrench that goes to a flare-end nut (exactly like a brake hardline), 10mm bolt on the subframe that goes to a holding bracket.

There are lots of writeups on rack depowering, including how to properly depower and plug sizes so you don't get crap inside the rack.

Yeah, either loop the line or use some metric plugs. Don't forget to turn the wheel lock to lock a few times first.

The hose is swaged on the tube with a crimped collar, if that's what you're referring to. It's not removable. I think you have to cut it in order to use the tube nut and the leftover tube.

I sold my pump for 35 shipped. Sometimes it takes a quick tightening before you can back it out.
