Another Electric Fuel pump wiring question.

I realize this is an old thread...but I did this(the OP's diagram) on my 86 2wd RC(440/OD833) with killer results.....start(ignition 2 in my thinking) runs the pump and run(ignition 1....again in my thinking) runs the pump as long as there's oil pressure.

Inertia switch in conjunction with oil pressure switch is the most efficient way IMOP...but in the RC there's a an old roll over valve that one would hope it still works. I wish I would of done this with the 64 Valiant.

Some safety is better than none IMOP.

Oh...I ran a circuit breaker also.
