Good post Mark. This is too serious an issue to ridicule you about. We'll save it for later.
Although I have an extinguisher, I also had some potential problems with fuel delivery that Jerry pointed out. I had a fuel filter in the engine compartment that was more designed for low pressure before the pump rather than the 12psi after the pump as I had it.
I have a question about the cut off switches. I have one, but if the engine is still running doesn't the alternator power the system even if you used the cutoff?
