How long does the car sit, to cause the carb "to empty"? What type of carb? My race car can sit all winter, and the Holley still has enough gas to start it up in the spring. Although I have always used electric fuel pumps on my race cars, but like the simple and reliable operation of a mechanical pump for street vehicles. Having an non running electric pump between the gas tank and mechanical pump would concern me as a potential restriction, and if the electric pump may possibly cause issues by "force feeding" the mechanical pump.
