hello, this is Sarge again about my Chrysler 300 C. I had the new fuel pump installed, but the motor still stalls after I filled the tank.I also had the charcoal filter done before I called you. I did as you said and still I am having the same problem. Is it must be something else.

Hello and thanks for using Just Answer/Pearl again, my name is Matt.
I have 12 years of experience at a Chrysler dealership, and have worked on the 300/300C since they came out in 2005.
I hesitate to contradict another expert, however I have some solid information for you.
I have seen this problem quite a few times. If the engine ONLY has the stalling problem after filling the fuel tank, the problem lies in the fuel tank itself.
What happens is...on the top of the fuel tank, there are several valves which control fuel vapors. One of these valves will tend to stick open. This causes the vapors generated while refueling to saturate the charcoal canister.
After refilling the tank, and after driving for 30 to 60 seconds, the purge solenoid will open to clear the canister. Since the canister has excess fuel, and the purge solenoid allows these vapors into the engine, the engine will stall at this time due to the excess fuel.
Normally the engine will stall once or twice, then it is OK until the next refuel.
The solution is to replace the entire fuel tank. The valves on top of the fuel tank are not replaceable separately, as they are molded into the tank.
I have replaced quite a few fuel tanks for this exact problem. The only other possibility is the purge solenoid is stuck open. I can tell you I have never seen a purge solenoid stuck open on 300C, and if it was, you would have the check engine light on and a fault code such as P0455 large leak detected.
Let me know if you have any other questions on this.

Hi Matt,My engine light does not come on at all, in fact this is the only problem I have ever had with my 300C, and the first time it started was 2 years ago while on a trip from Florida to Georgia. I sure hope it is not the tank, but if so it will have to be done. So far I have spent about $800 and still not able to solve this problem with the charcoal filter and new fuel pump.Well thank you for your help, I am about to retire from the Army Soon, so I will have more time to search for the answer.Thanks again,Sarge Blango
Thanks for using Just Answer. I'm sure a new fuel tank will fix the problem, based on what I have seen in the past.
HI Matt, I took your advice and ordered a new fuel tank. I am waiting for it to arrive, and will let you know if the tank does the job.Thanks, XXXXX XXXXX
