Charcoal Canister - Renewable?
With the SC engine soon ready to re-assemble, I was poking around the engine compartment and saw that the charcoal canister is sort of 'hidden", and thus has been forgotten.
Does anyone know if the charcoal can be "renewed", since I'm wondering if the activated charcoal is somewhat de-activated or used-uo after 22 years. This replacement is not mentioned in any service manuals, and it seems not to be for sale by any supplier. I know it handles the gasoline vapors from the fuel tank, but does it "wear out"?

Good question. In British car circles, for those of us with MGB's, we have been known to take the charcoal cannister out of the car, and open the cannister up (which is quite easy to do on a MGB). Then pour the charcoal in a pile on some concrete and then put a match to the granules to burn off the accumulated gas which does not hurt the granules as they are hard like gravel and not soft like charcoal. Many MGB owners do this as MGB owners are invariably cheap and inventive. You can also go to your local aquarium supply store and buy the same charcoal which is used in aquarium filters. Now the question I don't have an answer to is if this has to be done on a 911. At least this will bump your thread up to the top.

Cool stuff...does the charcoal can actually 'do' anything though? I've always wondered...does it make the front stink less by trapping some of the return gas vapors?

The purpose of the cannister was to prevent gas fumes from escaping into the atmosphere. They would go into the charcoal cannister and then be drawn into the intake manifold when the car is started.

And, to complement Kurt's answer, the charcoal actually is an activated charcoal, which is supposed to "scrub" the vapors of their harmful fumes.
And that was the thrust of my question. Since the charcoal "scrubs" the vapors, after some time it could be "full" and no longer able to absorb any more fumes. Does this truly ever happen, or does the charcoal actually "renew" itself by evaporation, etc. and thus able to continue doing its job? Does anyone know?
