Mike,
It is safest to not leave it energized all the time, hence the pushbutton. It should only be used for priming, like after the car has sat for a while and the fuel has evaporated out of the carbs. If you decide to eliminate the mechanical pump and just use the electric, that's a different story. In that case, you need to give consideration to how the fuel flow will be shut off in case of an accident.

Subject: Re: [Chrysler300] Electric fuel pump for 300-G
The ones sold by John are designed for continuous duty. My car already had a switch installed for a rear antenna (or was it the rear blower motor) and I used it because it was convenient, I usually turn it off, but have inadvertently left to on and wondered hat that noise was!

Using a push button is the best way to go. John Lazenby's company sells a good pump for the purpose. Larry, "a ding donger"? Mine chatters plenty enough to hear.

I have not found any of any type that will not work with the mechanical pump in place. The noisier the better so you don't leave it on when you don't need it. Radio Shack has an inline noise maker that you can plumb in parallel with the 12 volt wire that sounds like the ding-dong you hear when entering the 7-11. It costs about $12 bucks and you may need to insist that the clerk really does sell such a thing. They may not have sold one yet in their career

I wanted to add an electric fuel pump to my 300-G for easier starting. Any suggestions on a fuel pump that you have used that works with the mechanical pump. Thanks.
