Something more to add: It should not flood. Normally any extra pressure would be bled off through the return line on the mechanical pump. The original electric pump does not normally have enough pressure to supply enough fuel to keep it running. Back when I was running a carb, I switched out the electric pump to a pump from Napa and bypassed the mechanical pump. I did this because I remember back with my parents old Midas, that when the mechanical pump went bad, we bypassed with an electric pump, and the gas mileage jumped by 2 mpg. As it turned out, there was no mileage improvement. As a matter of fact, it ran rich. Slight increase in power, but it would blow fuel out the exhaust when you floored it. I put a regulator on, which helped, but eventually the regulator started to leak - yikes! I got rid of the regulator, and bought a fuel filter with a return line outlet. Hooked up the return line, and everything worked normal.
It should be pointed out that at no time did it ever flood. It always ran normal, although you could tell it was running rich. I think the quick and dirty solution for you would be to bypass the mechanical pump, and replace it with a fuel filter that has a return line. The filters are common as they were OEM for Jeep in the 70s. That should regulate the pressure correctly. If that still floods, then you probably have a carb problem.
