Could this be you?
I do private tours in Hawaii and have a lot of people sitting in the back seat of my customized Chrysler 300C
and I've discovered an issue that I was able to correct. This issue could cause fuel pump failure, stalling
and possibly (Heaven forbid.) fires. Child seats would also cause this problem.
I smelled gas inside my car and ignored it until after filling the tank, I saw
gasoline pouring out under the car in front of the rear wheel.
Is what I found was from people sitting in the back seat on the driver side
caused the fuel pump connector pins to heat up and melt around the
pins which opened the seal and allowed raw gas to leak out of the tank.
I changed my fuel pump only to have it happen again in 5 months.
The first sign your connector could be compromised is cracks in the plastic
fuel pump cover.
Upon further investigation, you may find your fuel pump connector is burnt. This is the beginning of the seal being broken and raw gas pouring out from your gas tank which could ignite.
On the passenger side because of people sitting there or child seats
pressing down could cause the top of the secondary fuel pump to
crack. Again, check the plastic cover for cracks then remove it and
check the top of the fuel pump.

I also had my car stall because of a passenger in the back seat just sitting
down caused the fuel pump connector to come loose. Nobody enjoys
being stalled in an intersection and I’m glad it happened to me and not
my wife. I would have had a towing bill and possibly a night or more
on the couch. I'm also glad I caught this before the car caught on fire.
