Start with the easy stuff and work your way from there. With the new e-testing their doing here rather than seeing what your car spews out, they're checking for engine codes, and it now sees if your evap system leaks. Go figure. What I've seen though is that lines may seem ok, but can have small cracks or such and leak. With the code makes me think there could be a crack somewhere. Also with smelling gas from the tailpipe, could it also be dumping too much gas into the engine or is it dumping gas and/or vapor through the engine rather than the evap system working properly?
The beatings will continue until attitudes improve!
