2002 Jeep Grand Cherokee fuel system problems

I was rear ended in my '02 jeep grand cherokee. My vehicle does have a manufactured installed trailer hitch. After the accident, it was apparent that the gas tank was still hit by the vehicle. The hitch did nothing to keep the vehicle from getting to the tank. There are visible graze marks where the vehicle hit the hitch and proceeded to the gas tank. Still not feeling safe from the chrysler recall that the "hitch" will prevent a fire hazard if involved in a rear end accident.

Vehicle was in motion and kept stalling on highway and city streets. Another computer was installed but didn't solve the problem. The throttle position, idle air control, and map sensors were replaced. Vehicle had hard start problem and the fuel injectors and fuel filter were replaced. Started vehicle in driveway and heard popping noises and it automatically shut down. The coli pack had to be replaced. Numerous vacuum hoses have popped off during driving and had to be replaced.
