Hello Walter,

With the pump shut off, you have a few seconds of fuel left in the
carb. With no oil pressure, your engine is going to seize anyway.
In a few minutes yes (and it will still run for some time after it's
damaged beyond repair), more than long enough off get off the road.
I'd put a big buzzer in and let the driver decide when it is safe to
shut down the engine. In some situations, I'd gladly cook the engine
to get to safety.
There is an override on the switch to turn the pump on anyway, but
it's a push button you have to hold down.
your driving down the road talking about programing language design and suddenly
an 18 wheeler starts tail gateing and another pulls out to pass. In the middle
of that, your engine starts to splutter, something it has never done before.
What is your reaction? I'll give 10:1 that it takes you a few seconds to
recognize that the fuel has been cut, remember that there is a switch to
override it, find said switch and push it. Now add in that you didn't install
the switch (it comes standard) and you have never taking the manual out of
shrink wrap. You starting to see why it will never come standard.
So tie it into the inition system or a tilt switch (some 4x4 do that
one).
It is tied to the ignition system already. The problem is, the
ignition doesn't automatically turn off when you crash your car.
Yes the ignition (as the the key) doesn't turn off but when the engine quits
running the ignition system (as in the magneto or that block of epoxy and
silicon under the hood) quits triggering the spark. Tie into that.
If you race cars, you are required to install a battery cutoff switch
on the outside in an obvious location. This is so emergency personnel
running up to save your a** can shut off the power first thing so no
spark or whatever will set things on fire.
I have a quick disconnect on my battery. Whenever I work on the car,
the first thing is always to disconnect it.
