RE: [Chrysler300] Cold start--Electric fuel pump

["Bob Jasinski" <rpjasin@xxxxxxxxxxx>]

OK 300 lovers, this recent discussion has brought to light a very
interesting suggestion from Bruce Paul that really is worth sharing.

His idea eliminates the need to add a switch at all!  Read our email
correspondence and judge for yourself.  As Bruce and I have discussed, this
setup could still be used to energize the electric pump in case of
mechanical pump failure by making an emergency connection to the hot side of
the starter relay.  Go to the bottom and start reading.

You are correct. I would have to move the wire about 1" from the start
terminal to the hot connection on the starting relay. That might be easier
than holding the pushbutton in for the time period that the electric pump
might be needed for actual driving, and it would leave both hands available
to be on the steering wheel. 

Besides saving a lot of engine cranking and wear on the starter motor to get
fuel to the carbs, the electric pump is definitely an accessory that is
worth having for back-up. It also seems to help hot engine restarting by
eliminating vapor lock.
