how big of fuel line do i need

One thing to consider when selecting a fuel pump is how much time your going to spend on the street.When I ran an electric pump I always carried a good used spare just in case for the long cruises to the beach,but with a mecahnical you can get a replacement at any corner parts store.If Im starting from scratch Ive always ran a 3/8 line with an electric as a pusher so I know I have enough fuel-but I havent gotten that far with the duster yet.
