Q: Gas smell inside cab

I have a Werks turbo kit on my 2.4. When I lifted my foot off the pedal after a firm acceleration I smelled gas for a couple of seconds. Then it was gone right away. It really bothered me. I looked under the hood a couple of days ago and noticed one of the 10 mm bolts holding the fuel rail down was coming loose by approximately 1 cm. I just tightened that when I put the engine in at about 2500 miles before. I went to the gas station this morning and while I was pumping gas I opened the passenger door to get the garbage out from the floor of the car and noticed a gas smell inside the cab. I didn’t smell it before filling the tank. I just remembered that during a hail storm a few weeks ago the driver’s quarter panel was hit by a high velocity softball sized piece of hail just to the left of the gas cap. Now the gas cap door doesn’t close. I remembered seeing on the dashboard a Check Gas Cap warning light. And when I am coming to a stop the engine will rev up to 2500- 3000 rmp for a few seconds. I noticed the Blow Off Valve stuck open. I turned the car off and the BOV was shut. I turned the car on and the BOV was slightly open. I revved the engine up got out of the car and the BOV is open about an inch. Do you have any suggestions or ideas? I don’t see any other damage except near the gas cap. The fuel rail looks good. I don’t see any cracks.
