Re: [Chrysler300] Winter Nap

[Rich Barber <barber@xxxxxxxxx>]

I had the same problem with my 1955 C30.  It was solved by installing a 
rebuild kit in the fuel pump.  A previous mechanic had replaced the 
diaphragm with some improper material that did not flex very well and 
the check valve was also apparently leaking and allowing fuel to drain 
back to the tank.  Poor pump performance then delayed pulling fuel into 
the emptied line until RPM was established by priming.  Now the big 
brute starts on about half a crank.  I think replacing or rebuilding the 
pump is a better bet than blowing air back down the line.  I understand 
there is a filter or screen on the intake line inside the tank that 
might be plugged, but air pressure would probably blow it off and give 
you only a temporary fix.

The point has been made that current fuels and most old fuel system 
synthetic components are incompatible and this can cause deterioration 
of the soft fuel pump components.  Avoid NOS pumps in favor of recently 
rebuilt or recent rebuild kits to get modern materials not soluble in or 
embrittled by modern fuel.

Enjoy your F this Spring.  Keep us posted on how you resolve your lack 
of fuel problem.
