Last year I saw an accident where a SUV had flipped on its side, and the wheels
were still slowly spinning, because the engine was still running.
So I would lean towards the inertia valve.
I guess it's especially important if the pump is back next to the tank. If the
pump were close to the carb, a break in the fuel line behind it would not be
such a big danger.
Or just use a stock mechanical pump. That approach has always worked fine for
my car :-)
