I had nightmares of that line. I removed my flexible hose last year and it would not come off. so I had to cut the line you are referring to. I replaced my flex line with the Russel G body kit they sell. and Got new lines for my axels from classic tubes. Your first option is call Classic Tube and tell them you want to buy just that line separtely and be done with it. I opted to bend my own(Not a good idea.) I bought two tubes incase I messed up and yes I did. The second bend I got closer and made it fit. The problem is, that bend right as it goes through the frame hole is a very tight bend that you cant do with a regular tube bender. I finally got it to fit in and tighten up to the threads but it was a bitch. I would have ordered the piece from Classic Tube If I knew I needed it at the time. Your picture shows that is is completly rusted I would just get the whole line from the Diverter valve back replaced you probabbly need it.
