I want to add a small activated charcoal canister on my gas tank vent. Is it just activated charcoal in the canister? Thinking something very small any thoughts?

The "trick" with an evap charcoal canister system is purge flow during operation.
This dries the charcoal out. It is just normal activate charcoal, nothing special. It acts like a sponge that requires drying out during use. Everything in the world uses a purge valve and engine vacuum to dry the canister except. The stock T4 914s... Adding airflow from the cooling system directly into the canister and venting that into the air filter housing is the EASIEST evap system I've seen yet. It's Genius! (IMG:style_emoticons/default/first.gif) You could vent to the air filter OR you could vent to the atmosphere. It would only put out vapors during use and as long as you vented those correctly you probably wouldn't ever smell it. Personally, for a street-based car, I'd vent to an air filter and ingest the high-end hydrocarbons. When the very first emission controls were added back in 67-68 they got rid of nearly 70% of the emissions with two simple systems. PCV and Evap. Evap from gas tank was worth 35% of total emissions... I want to eat my stink! KISS it... Just adapt something like a late 914 system into your car. |
