If you decide to go with a different tank and an electric pump, check out
https://www.revolutionelectronics.co...Fuel_Pump.html for a controller. Also you should install an inertia switch to kill the pump in case of an accident. Late model Ford vehicles have a separate switch, usually mounted on the passenger side kick panel that works nicely. I see original tanks advertised on other sites in the $300 range, maybe you could replace your tank and sell your original bad tank to someone who wants to cut one up.
