Looking for Tips on building a fuel system
Are you using today's crappy pump gas? If yes, then I would run the bare minimum amount of rubber fuel line as the alcohol/methanol content in today's pump gas swill will quickly deteriorate rubber fuel lines and aluminum parts in your carb.
I recently read an article saying one foot of rubber fuel line can lose 1 gallon of gasoline per year just due to fuel permeation. 20-feet of rubber hose equals a tank of gas per year - and that vapor will probably be in your garage.
I'd do as much solid line as possible, but if you're going to run rubber hose, even braided hose, make sure it's some sort of "vapor-guard" quality. It's more expensive but worth it.
