I got the AC hoses from Phil at Fastlane. I was told by a couple of mechanics that the rebuild hoses will usually leak in a year or two. So overall your better going with new hoses.
All the hoses that I got from Phil were OK, Except the manifold hose on the W123. The first one would not give a good seal on the compressor. The second one did but the other end was not curved correctly and I could not mount it to the engine side. So I reused my Mercedes manifold hose. ther is a difference in quality between the hoses from phil and the mercedes hoses I took off. But the connected corectly and sealed so I don't have any real gripes about then, Of course except the manifold hose.
