Bruce,
Just fabricate a new one. Not a big deal. You can get bulk tubing and fittings and then just bend it up to match the original. I doubt you'll get a used one in really great shape, nor do I expect you'll be able to find a NOS replacement.
I put a '97 Grand Prix on the road for Noah last Fall and we had to fabricate some replacement brake and fuel lines, and it was no big deal. They ended up looking as good or better than stock, and the newer materials are supposed to last better than the originals.
Cheers!
Sean
