Re: [Chrysler300] 300C vapour lock?

Hi Oddvin

Two possibilities that have not been pointed out that could be your fuel 
starving problem. 30 years ago I battled the same problem on a car I owned 
at that time. It was the in tank fuel filter on the end of the fuel sending 
unit/ pickup. This is quit often over looked as it is out of sight out of 
mind. These filters are a fine Nylon mesh with age will easily clog and 
restrict fuel. Unless you have changed this I suspect this could be your 
problem. At least you would want to eliminate this possibility.
The other is the fuel filters at the carburetors. That is an easy test as 
you can remove the filter elements temporarily to see if that resolves your 
problem. I have stock of both items NOS if you cannot find at your end.
