I have an 87 Fiero GT with a completely blown AC. Compressor is leaking like a sieve, and the hoses coming off the compressor are leaking with cracked crimps. Needless to say, I'm just gonna rebuild the whole system. As part of this rebuild, I want to "rebuild" the AC lines that contain flexible (rubber) sections. I know that the line from the compressor to the rear manifold is rebuildable, but does the long AC line running under the car contain a replaceable section or is it all metal. I've look at some parts diagrams from on-line parts houses, but the ones I've found describe the long, undercar line as "all metal". Is this true? Are there others that can be rebuilt? One option I'm pondering is to purchase some used lines from a salvage yard and rebuild those, but I need to make sure which lines I need. Any help anyone can provide would be appreciated. Also, if anyone has the proper hoses I need and are willing to part with them, I'm listening.

I had a local ac hose place makup new lines for a 1997 Land Rover that I had the hoses for but the ends were broken off or damaged. It cost me only $26000 for all 4 hoses.
Also you can try this place that supplies hoses and fittings:

The under car lines are mostly metal, one has a short rubber section at the front compartment. The lines off any 85-88 car will work in your 87 GT, if you re-use the hoses that go to the compressor and get them re-crimped.

Most shops Will Not "re-crimp" AC soft lines because of old rubber often has problems and not legal to use now.
The shops need new Barrier Hose to seal R134a and R12 better the old hose.
Main problem for hoses is engine to frame hose set.
Gets cooked by the exhaust and leaks at the joints where hit the metal but Any oil leaking at any point the hose is bad and needs to be replaced.
Hoses are likely not the only problem.
Like AC compressor can leak and when is in the shaft seal, hard to see by any method. A sniffer may find that or not depending how bad the leak is and work area at the time tested.------------------

Yes, new hoses and crimp fittings will be needed. Depending where you live, cost of this service also frequently exceeds the cost of the parts and the specialty crimping tool.[This message has been edited by RWDPLZ (edited 06-25-2019).]

Thanks for the tips everyone. I reread my post and I wasn't clear. I plan on taking the hoses to a local professional shop and having them rebuilt with new barrier hose and crimped. I just wanted to make sure that all hoses that can be rebuilt are taken from the car. I'd sure hate to get the system back together and find out I missed a hose. I don't know the maintenance history on my 87 GT, so I'd rather be safe than sorry.
