[345 DeSoto]

Leave your fuel pump hooked up/working, and install a 6V flow through type electric. I got mine from Sacramento Ford and have a toggle switch under the dash. Key on, switch on, and let the pump fill the carb, rather than using the starter to do it. Fires right up, then switch off. When idleing, or in the blazing sun, hit the switch...prevents vapor lock, and the pump is low enough pressure so that it won't overpower the carb float if you prefer to leave it on...or forget...
