Pulling stuff out of my 74 cj5. Is this a exhaust filter or something?

Ok this thing. It was right up against the firewall on the drivers side under the hood.

Actually, it *is* serviceable. You can replace the charcoal inside with new activated charcoal from a pet store (for aquariums). In doing some research a couple years ago I found that the older canisters like that are fairly rare and pricey on eBay. Folks restoring mid-70's muscle cars pay top dollar for them. Of course, it doesn't hurt to clean it up and re-install it on the Jeep. It serves a useful purpose in recovering gas vapors evaporating from the tank and it doesn't rob engine performance in any way.

Here's my write-up on rebuilding mine: http://jeep.smallcraft.net/canister/

Muffler bearing.

It will stop you smelling petrol vapours so worth fixing and putting back on.

Not doing anything in that condition. Replace with one from a WJ. There's a write up on here somewhere. I did it and it worked great/better.
