RE: [Chrysler300] Electric Fuel Pump

[Ryan Hill <ryan_hillc300@xxxxxxxxxxx>]

Rich, just a quick comment about using your electric pump as backup if the mechanical pump fails. Often, when a mechanical pump fails it allows fuel to leak into the crankcase. I would imagine you could end up pumping fuel into the engine while you're driving it on the auxiliary pump? In this situation I would bypass the mechanical pump to limp it home.

I installed an electric fuel pump near the gas tank and wired it so that it
would only run when a button switch hidden under the dash is pushed, the
ignition key is in the crank position and the gear selector is in drive so
the engine will not crank. I only use it when the car fails to start
immediately. I can hear the electric pump running and when the pitch
changes, I know the carbs are full, the floats are closing the float valves
and the car is ready to start with one pump of the accelerator pedal. I
left the rebuilt mechanical pump in place and fuel flows through the
electric pump when it is not running. I also added a pigtail that could be
connected to a hot terminal for continuous running in case of a fuel pump
failure.

This has made all the difference in the world in having confidence the car
will start easily during any condition and I do use it about 50% of the
time.

Subject: [Chrysler300] Electric Fuel Pump

Hello,

I would appreciate any suggestions for a good electric fuel pump for a
3256SA Carter AFB.
After the fuel pump is installed, is it common for the push rod to be
removed from the stock pump?
I am still having to crank the engine a lot to get fuel to the carb on cold
starts.

I believe the best place to mount an electric fuel pump is near the rear
axle?
Any other suggestions?

Thanks,
Mark Lindahl
