DV,
My
oil pressure switch is wired in series with the fuel pump relay. If the engine stops (or otherwise loses
oil pressure), so does the fuel pump.
I'm not arguing an inertia switch wired to shutoff the fuel pump (or the ignition?) is a bad thing; just trying to decide if it is "better" than the
oil pressure switch I presently have.
Pegasus offers both the inertia switch AND the oil pressure switch as fuel pump shutoff safety devices. Maybe it would be safest to have both.
