Electric vs. Mechanical Fuel pump debate

I run an elec pump. I run it off of a relay, through a ferd fuel pump safety impact/rollover switch. Also running to this relay is a very very small switch hidden in reach of the driver seat to shut off said pump, for leaving the car parked. This way it also doubles as a theft deterrent. Because if your car is broken into to be stolen and they can't get it, and they rip out the dash then any destruction is generally called vandalism. Now if they get the started and out of the driveway it's theft. Different coverages by different things. Plus if the car runs for a second then won't restart they might think it's just a p.o.s.
