Has you problem been solved? I once had this issue, I started to feel petrol smell inside cabin. I checked engine bay, it was clear. I checked under seat (as my civic's fuel pump is there), nothing there too. I could not figure it out. After 7-8 days when I went for refueling, I found out that the fuel cap was not tightened properly. After refill, I got it tightened properly and the issue was solved.
Do check you fuel cap for leaks.
