I like it, too, but I haven't been able to visualize how one would go 
about doing it.

If you mounted an electric pump under the gas tank, in series with 
the gas line to the engine, then it would push gas thru the 
mechanical pump and into the carbs when the electric pump was 
energized. This would work, however, only if gas can flow freely 
forward thru the electric pump when that pump is off. I don't know if 
they work that way, but you could tell by trying to blow thru one.

A momentary contact switch would make the crash safety switch 
unnecessary.
