I don't think there were any banjo bolts on those fittings. They are simply threaded fittings with steel pipe ends that the fuel line clamps on to. Any fuel line will do. Go with Viton or something similar if you want the best, otherwise, go down to Napa or Autozone.
For the fittings, start here:
Should look something like the threaded piece in the picture. This is part no ESR 267. This is what I found in 5 minutes. You can probably find the exact pieces with a little more searching. IIRC, the 2.5NA fittings moved right over to the 200TDi. Do you have your old engine still?
