ROCKAUTO FUEL TANKS

The tank doesn't size the fuel line, the pick up you install does, could be 5/16 or 3/8. If you go with the 3/8, if you decide to go bigger engine it'll save you a job of changing pick up. You can adapt 3/8 P/U to the 5/16 lines. You can never have too much fuel at the carb, since it regulates how much you're going to burn. To take advantage of 3/8 P/U you have to change all the line to the fuel pump. Since a lot of guys have being doing F.I. the 3/8 line is a good thing. Just food for thought.
