Fuel Tank Vent

[neki67]

what do you do to help the gas oder during the hot part of the summer?
Sitting in my garage I can smell the gas venting out of the vent tube.

If memory serves me correct, John (II Much) Parson put an (aquarium) charcoal filter at the vent tube to stop the smell. I believe it is somewhere in the II Much built thread. Use the search function, I'm sure it will pop up.
