Another aspect to consider. The updraft carburetor needle and seat is designed to only handle fuel pressure under a gravity head of less than a foot, and an electric fuel pump feeding directly to the carburetor will OVERWHELM it and profusely leak. There are folks with Detroit Lubricators that use an electric pump to feed the vacuum tank when the car has been idle for a time, or when a little more is needed when vacuum is low (like climbing a long hill) but feeding the carb directly is not likely to ever be satisfactory.
