What they told you then, and if anyone is still telling the same story now, is and was completely full of crap. There's no need to even change the o-rings on lines or fittings you don't open, unless they already leak.

It was a huge scam that made a lot of people rich, Dupont was one of them. If you want to replace the hoses, buy a length of generic a/c hose and the fittings you need to splice it in. I'll warn you though, you probably don't have the correct hydraulic presses needed to do this. We build hoses everyday at work, and I can't see anyone having those tools laying around thier garage. It isn't like splicing a coolant hose.
