Gasoline smell in cabin
I just repaired a similar issue today. In the trunk is the vent line that goes from the filler neck thru the trunk floor (67 Dart). The tube on the filler neck and the tube that loops around and parallels the filler neck were not aligned properly and over the years had degraded till there was a gaping holes in the rubber cuppling tube.
Every so often I would open the trunk and get a wiff of fuel. It's a convert with the top down so I don't know if it could be smelt in the cabin.
I aligned the tubes and replaced the old rubber cuppling tube, no more issue.
Not saying this is your issue but worth looking into.
