Weeping fuel lines

Well after about six months of burning B-100, my rubber fuel lines (as predicted) are weeping copious amounts of bio-diesel. I'd like to replace them with synthetic. Anyone ever changed all their fuel lines before? Any advice or instructions would be greatly appreciated.
Just in case anybody is wondering my truck is otherwise running very nicely on 100% bio-diesel which I purchase at the pump of a local gas station. I drive up, fill up, pay up, and drive away with a much cleaner burning fuel that is American grown.:cool2:

i had the same problem, the gates fuel hose they sell at napa can not handle b100 even though it is the nitrile stuff jdemaris was talking about.
you will probably have to go with viton. I just got sick of it and stopped using b100, instead i cut some kerosene in with it as i did not feel like dropping that kind of money on viton and i run mostly grease anyway.

I did find that those short lengths of fuel line by the tank and connecting the steel lines along the frame rail were just fine. It was only the newer gates hoses i had added a while back that weeped.

i wonder if the nitrile stuff they sell at mcmaster is any different than the kind i got at napa - anyone know?
