RE: [Chrysler300] Re: AUXILLARY FUEL PUMP

["Bob Jasinski" <rpjasin@xxxxxxxxxxx>]

That's why you use a push button switch, don't leave it turned on, and only
use it for priming.  Sorry to disagree, but I've had an electric pump on my
G for 30 years and have never had a problem.  If you have a failed diaphragm
in the mechanical pump, the engine won't run.  Of course, you could always
eliminate the mechanical pump entirely if you wanted to, but I don't want
to.

I would never run an electric pump before the mechanical pump because ... On
numerous occasions when the mech. pump diaphram failed due to mod. fuel it
allowed a direct passage to the engine oil sump. I cannot imagine what would
happen if the mechanical pump failed and the electric continued to pump and
the car did not stop for several miles ........?

Many of us have run electric pumps alone that way without incident but it's
dangerous if you're running a mechanical pump as well, especially with
modern fuels that seem to deteriorate the mechanical pumps faster than in
the good old days. 

Also, if you're running an electric pump full time as your only pump on a
carburated car, I would think you should have a low oil pressure kill switch
or inertia switch installed in the event of an accident where the key is not
turned off. Nothing like having a fuel line rupture and a pump continuing to
run and spray raw fuel all over.

like this. If the electric pump is left running and your mechanical pump
fails, you could potentially fill your engine with fuel. (If the diaphragm
fails, it will leak internally) The damage can be catastrophic! Also, in the
past, some have mentioned the convenience of having a second pumping source
to limp home on in the event their mechanical pump fails......this should
only be done after bypassing the mechanical pump for the same reason.

way back when, we used to just wire the pump to the 'hot when key on' 
source that way if the key was off and out the pump was Not running
