Fuel Guage Sender Replacement - Fuel Odor

[Threev8s]

I had the fuel guage sender replaced by the dealer today, and after filling it up, it's functioning properly. But, right as the service rep handed me my paperwork, I was told that I should leave the windows open for a couple hours to air out the fuel odor. I drove around for quite a while, mostly at highway speed, and then let the car sit with the windows open for a few more hours. It still has a strong fuel smell. From what I could see, it looks like they might have accessed the fuel tank behind the rear seats via the interior, as the seats were tilted all the way forward when I saw my car. Also, I brought the car in with the tank less than 1/4 full. Did they do this repair correctly? Should they have accessed the tank via the interior? I have not heard of anyone else with residual fuel odor after getting the fuel sender replaced.
