It's probably from living in Florida but I'm stating to see drying and cracking on my fuel line. I'm talking about the hose that runs from the petcock valve to the carb. Now I know I can get an original replacement for about $8 but why give up the chance for more shine? I'm thinking I will go with a stainless braided line. Therefore the question: Do I need 5/16 or 1/4 inch line? I can't find any reference to tell me so any help will be appreciated.
