I just patched the leaking parts on mine. You don't have to follow the exact routing of the old lines, but you do need to keep them away from moving parts and the exhaust.
I will have to do this shortly. I think I have a weeping line, does anyone have a supplier for stainless fuel lines? I would rather spend the money on materials and do it onceIt was a bit finicky to get it sorted out, but after taking out the battery box/cross member and spending way too much time cursing, it all went together pretty well.
