Do you smell it in the trunk also?
Under the rear carpet are 2 access plates. Under one (right side) is the fuel pump and gas gauge sender. The other side is a second sending unit. Both are secured with a large plastic ring nut with a large o-seal under it. Both of these, of course are direct passages to the gas tank. Might be worth a look and smell around these...fuel lines connect to right side (at fuel pump) also.
