So how does this system work? Review these first two graphics from the factory repair manual to find out.
(PS I wonder why the forced induction guys dont't use the air from the fan housing to spin their turbos? (IMG:style_emoticons/default/confused24.gif)) Attached image(s)

Well Pat...
You can see the factory manual recomendaiton above indicating replacement at 50K intervals. Thats all I know. I dunno nuthin' 'bout the mineralogical properties of the activated charcoal, bet Google knows. I believe its primarily an emissions thing...filtering raw hydrocarbons from the air (the fuel tank is not pressurized, its open to the atmosphere). If people smell gas in their cabins, it must be a faulty hose, loaded-up charcoal canister or some other flaw in the system. OR, you could find an NOS charcoal canister correct for your model year...OR you could locate a later-issue <gasp> plastic canister and change out the charcoal as in the above picture. Next chance I get I will post photos of the different styles of canister and their different locations... How many different canister styles were their? How many different mounting locations?
