David,
I'm not exactly sure how this thing works, but in Bentley it looks like the
VOCs must pass through the charcoal canister BEFORE they make it to the air
intake system.... the VOCs attach themselves to the activated charcoal....
the way I understand it the VOCs would not make it to the air intake system
until after the charcoal is saturated and can adsorb no more VOCs....

...correct me if I'm wrong because I'd like to understand this vapor
recovery system... and make sure it's working as I don't need any more
migraines than I already get :)
