gas fumes in "69 beetle

[gotabeetle]

I just took my 1969 Beetle out for the first time since spring. There was a strong smell of gasoline inside all the time I was driving. The gas tank was full when I stored it for the winter and it is still full - so I don't think there's a leak in the tank. Any other ideas of what's causing it?
Thanks

have you checked your gas lines? or the vent hose in the filler neck? even a pinhole can be enough to produce fumes.
