electric fuel pump safety

my plan is to run the manual or the electric, not both. I understand your setup, but im not sure i would have to run a bypass switch if the fuel bowls were full on start up. once the engine fired, the pump would kick on. the wiring schematic is printed with a oil switch in the Holley instructions,and even gives a Holley part #. I guess my question is, how many people run an oil preasure switch? it seems unsafe if you had an accident or a fuel line rupture, that pump would keep pumping.
