I had the same issue with a fuel smell near the filler neck. As it turns out, the piece circled in red (see pic) was rusted out, and was leaking fuel. I replaced it and the smell went away.
There's no pressure regulator in the quarter panel, but there is the evap manifold that helps to manage fuel tank pressure. The gurgling you heard may have been fuel draining back into the tank from the evap manifold. I've spent enough time messing around in this area to know that there's sometimes a fair bit of fuel in those evap lines.
