To help people answer your questions more effectively:

What fuel lines are you talking about? From the tank all the way to the front of the car?

If you want to replace your rubber lines they are all 5/16". If the one on the tank screen is an OEM one, you can unscrew the hose from the tank screen, when the tank is empty, and cut the crimped fitting off. There is a normal hose barb underneath the crimp. All you need for the job is a screw driver and a lot of rags., and maybe a razor for the tough ones. If you are running biodiesel you might think about viton hoses. You can get bulk hose or hose kits at www.greaseworks.org. You'll need about 5' of hose for the job.
