    Replacement charcoal Canister Question

    Does anyone know of a source for a charcoal canister. Mine appears to be plugged.
    Or can you take them apart to replace charcoal.

    What test did you use to determine it was plugged?

    I blew in the 5mm port with my mouth and it felt plugged, no air movement. Blew in both larger ports with my mouth and they were clear.

    I've heard that you can bake them back to health. Never tried it so don't really know. It should only take gas fumes so hard to imagine what could plug one up.

    I opened up my canister and discovered that the small screen at end of 5mm tube was plugged. After soaking and using a dental pick I was able to clean the screen.
    Air now blows easily through the tube. I now plan to put new activated charcoal back in and reseal the canister. Since you can't buy these charcoal canister it seems like you have to fix them if you still want to use them.

    Covid -19 boredom job! Refurbishing a charcoal canister. After cleaning plugged small tube I refilled my canister with new Charcoal. I was told that automotive charcoal is different from aquarium charcoal. So I bought the cheapest charcoal canister I could find which was a VW van charcoal canister.
    Now there wasn't quite enough charcoal in the VW canister so I had to use some of the old charcoal.
    I reassembled the canister using JB Weld. After that was dried I finished painting the repair with Por-15 just in case there was a pin hole in the JB Weld.
    All the lines now blow easily although the small tube feels constricted because of its small diameter.
