Great video. Would it matter if the car is carb’d on a 4?

Would work the same as long as the downstream end is dumped into an air cleaner like the original setup. As was said earlier, some hydrocarbons surely escape from the charcoal and the charcoal probably doesn't adsorb 100% of what goes through it, so the effluent out of the canister is going to have some residual that should be burned.

I've also read about re-activating carbon by heating it which supposedly re-fractures it to create new surface area but that seems like wasted effort. i like the fire starter idea. It's tempting to try at the risk of losing one's eyebrows.

Thanks for the great video. This was one of the easiest fixes I've done so far, hardest part was unbolting the canister. The new charcoal pellets are about 3 times the size of the original ones, took two of three bags to refill. I left the old pellets outside 3 days ago and they still wreak of gas fumes (I think they were past their limit). So far so good on no gas smell in the cabin.

I know this is an old thread, but just a note to say the video is still of great use. Easy and pretty cheap project, and I went ahead with the cleaning up and repainting of the outside of the canister, too. Thanks.

Since the mechanic that installed my electronic ignition advanced the timing 5-8 I don't seem to be running real rich anymore but when I FIRST put the heater on I do seem to get some fumes, open the window and get fresh air then close it. Is this the purpose of the charcoal box to filter out some air from the passenger cabin?

No. I believe that task is for that little round plastic insert in the door jamb. (IMG:style_emoticons/default/beerchug.gif)

No. It could be some oil dripping on your heat exchangers but it would be a good idea to pressure test your exhaust and at least use a CO detector in your cabin.

No. It is to stop gas tank vapors from leaking into the atmosphere. It sounds like you may have oil contamination in the heat exchangers or the heat exchangers have an internal leak and exhaust vapors are entering the cabin. This is extremely dangerous an should be checked out

my car stinks in the engine space . . . .

What are you guys talking about? The smell of gasoline, oil and unburned hydrocarbons 1st thing in the morning is what vintage cars are all about. (IMG:style_emoticons/default/laugh.gif)

New cars have to meet such strict evaporative emissions standards that we've all forgotten what "real" cars (and real Hot Rodders) smelled like back in the day.

Great video -- I've never seen this done and always thought it would be do-able. Glad to see someone tackle it and document it. Great Job.

Great! Have been wondering how to do that for about 30 years...
Have three additional tidbits to contribute:
1. Might want to clean that filter to ensure good air flow. A little Dawn and a medium stiff brush worked for me. Be sure to allow to dry thoroughly before reinstalling.
2. There is ALSO a little filter in the bottom end (see photo). Be sure to remove and clean that one, too.
3. My local pet/fish store carried the pellets (see second photo). A bit more than needed, so correct amount the cannister needs is 35-40 oz. Supported local business.
Onward!
