While I agree with both of you about gas evaporating, I think I disagree that this is causing the strong smell. It is worse than it has been in the past recently, and if the tank is full I will get some gas bubbling out of the short metal vent line. Gas on the garage floor is definitely not what I want in the house-attached garage.

Maybe the idea of a small fuel filter on that vent line is not a bad idea. Anyone else tried that?

Thanks,
Darren
