I would like to know what, if any, shut down systems you guys are using for electric fuel pumps? I would like mine to shut down if the engine dies. I have considered using the inertia switch from a Ford and also wiring a relay into my stator. Ford alternator with external reg. I am not sure the 8-9 volts from the stator is enough or if that constant load on the stator would be damaging. A prime button isn't a problem.
