Agreed.

I don't suggest plugging up your tanks with visqueen. Good way to create pressure on the tank. If you don't close the valve, it will just vent the pressure through the carb and force fuel out. If you do close it, it will just expand and pressurize the tank. Good way to make leaks, or worst case bust a tank. They are vented for a reason. Not just to allow air in as fuel is consumed. Plastic gas tanks will vent if pressurized enough. They aren't air tight.
I still say open a window.......
