I just recently replaced the original plastic surge tank with a new aluminum tank. I replaced the hose with a high temperature silicone (the blue ones). It was a straight piece, about 30" long. can't remember the diameter, however. I got it at a local hose shop, but I'm sure most auto parts have them.
