Nils,
I don't like to be serious but ...
gasoline fumes are 6 times heavier than atmosphere that means if you smell it you only get a hint of danger. The proper mixture of air and gasoline has the explosive potential of slightly less an dynamite.

The canister and the carbon inside that the fuel tank was connected to has passed it usefulness years ago, it doesn’t matter if it connected or not. The gas tank vent must allow air to enter if fuel is to leave the tank. I connected my vent to the air cleaner on the inside of the filter element. The paper isn’t the best barrier but it does offer some resistance. Also keeping the hose as high as possible keeps the fumes from escaping.
I suspect that by leaving the hose low in the engine bay that it might be possible to siphon the fumes off of the tank. (not sure)
