I think he is saying that most modern cars use both. If either one detects trouble, power to the fuel pump is cut.

We could do the same. Just run the wire providing power to the fuel pump thru the oil pressure switch, then thru the inertia switch, then to the pump.

Here is a picture of the inertia switch just installed on my '37. I was planning to use an oil pressure switch, but then on advise from others here, decided an inertia switch is a better safety device. This switch was pulled from a junkyard Mercury Sable. Easy removal. Is now mounted in the trunk of the '37, on the spare tire platform support. BTW, those big red knobs were on the switch, I guess to draw attention to it's existence; I put them back on to serve the same purpose.
