Re: electric fuel pump to assist starting?

Though I have never had the need for anything other than the factory mechanical pump I can see why some folks want one, especially if they live in a hot climate or are prone to vapor lock. In my view they should be wired to a "dead-man" type switch which requires you to keep your finger on it if you're pushing thru the mechanical pump because more than one engine has been lost when the mechanical pump diaghram sprang a leak and you didn't know it so you keep blissfully driving along. Eventually enough gasoline may dump into the crankcase to dilute the oil, wipe out bearings etc., with an occasional underhood fire with horrible consequences. If you add an electric pump, just keep this in mind!
