Vapor canister charcoal filter. The one in the engine compartment by the fender.

I bought the small round white filter element that apparently goes in the bottom of the canister. No problem there.

I also bought one of these from Rock Auto (WIX 42291 Carbon Canister Pad) it looks like it should go inside the can...but the can is sealed, no way to get in.






Can someone tell me what's inside of the canister for a 71 Buick gs? Mine is empty, except some cobwebs and what may be the scattered remains of an old filter?

If its only activated charcoal inside with the bottom filter holding it in, where can I get some of that?

Thanks!

My buddy refilled his with activated charcoal from a pet store. Thet had coarse stuff about like original.

 

Thanks John ill give that a try

 

i have take a look at my old canister

 

That's great, thanks for the pics. So you just pack that thing full then put the pad on to hold it in?

 

i have the car since 2004, do a frame off resto since 2008
never looked into this canister before i see this thread, maybe this is what GM put in 40 years ago

 

Yep, just activated charcoal (fish tank stuff) and then put the yellow 'fiberglass' filter in the bottom. That's all there is to it.

 

Thanks everyone!
