You can easily rig an electric pump up to a hobbs switch (loss of
oil pressure) or an inertia switch to shut it off when bad things occur. I have a hobbs switch on mine, but believe that an inertia switch, or both for that matter, is the way to go. I run a Mallory 140 GPH with no problems at all. My motor makes 450 or so flywheel HP. This is a very quiet pump too. Aeromotive makes some nice products too.
