Post Over fueling

Car is my 84 RX7 with a 12A

This was my surprise... well at least it was to me. I go to start my car to empty the last of the fuel out of the fuel system. The fuel pump is disconnected (wires cut awaiting a factory style replacement). So here is my question what would cause the carb to fill to the brim with gas?
My assumption is a fuel pump pushing to much fuel to the carb. Aftermarket pump routed in the car hooked up the auto trans connector by the shifter.
If I am right then I am assuming that would cause about .25-.5 gallons of gas to end up on the floor of the garage by going out of the exhaust system I do have to admit I found all of my exhaust leaks this way.

So to make this short as possible since one of the PO decided to replace the pump halfed ass it over fueled the carb causing fuel to come out of the exhaust of the car. If I replace the fuel pump and do it correctly then my fuel pump will not over the fuel the carb and that should correct my over fueling issue. Is there any other things I can do to prevent this from happening again?
