You can do it but you'll need a small tank up front, for the fuel and an electric pump to fill the small tank. If you ar running carbs the electric pump will work o'k from the rear tank, but if you're running a mechanical pump you will definately need a small tank up front. I've got a duel setup on my car i can switct to a carb and run gas in a matter of minutes, from the rear tank but since i run alcohol with a mechanical pump i have a 3 gal tank mounted in the front.
