Putting metal lines in adds stress fractures into the picture. Break one and you may be screwed. With how much these diesel engine shimmy in the engine bay I wouldn't put in hard lines.

I got my viton hoses from Greaseworks.org. Justin is a great guy, and runs a good operation. He basically makes a kit for you. He precuts all the hose and labels them so you know where they all go, and includes all the hose clamps you will need.

I have had B100 in my car for 8 months/10,000 miles and haven't put my vitons on yet. My fuel lines look just fine, no signs of degredation yet. But they may have been fairly new when I bought the car.
