I have a 1923 Columbia it has a six cylinder Continental engine with a Stromberg updraft carberator and I put an electric fuel pump with a fuel regulator in it. At idle even with the regulator turned all the way down it floods the carb out so I was thinking of going back to the vacuum pump but keep the electric for when I need it. I am just not sure how to go about doing this.Do I run one fuel line from the tank to the vacuum pump and another from tank to electric pump and then to vacuum pump or will the vacuum pump pull the gas through the electric pump and regulator or two different lines to the carb? I guess I am just asking for help. Thanks in advance Bob
