Do they go bad?
How do you tell?
Where to you get em. I'm replumbing my 72 Dart. I've got the original, but have no idea if it's good or not.

Thanks!
Jason
 
That's a VERY good question. They usually fell off of whatever cars they were on, LOL.
 
On my 73 Dart Sport I started finding little balls of charcoal under the hood from the canister. I tossed it and added a rubber hose and routed it into the front frame rail. Basically the way OEM is for the rear filler next vent,
 
Great question, I've never heard it talked about before. My guess is that just like a filter drier on an AC system, once you mess with it, it needs changed.
 
Dont know if the charcoal ever wears out. There is a filter pad on the bottom that can be replaced. I got one for mine at Advance. It also keeps the charcoal from falling out.
 
The charcoal canister can fail in two ways.
1) it can become Saturated with every carbon atom having fuel attached to it., and
2) The carbon starts to leak out

As to the former the canister gets very heavy. Theoretically the fuel vapors should get pulled out every time the engine is running and warmed up. It doesn't always happen, as the controls and/or hoses can fail, or the dust filter at the bottom gets plugged.And I suppose there may come a time in the life of the carbon that it it just fails to let go of the vapors.
As to the latter, you almost never hear of that happening.
I have heard of them becoming moisture-laden,tho.
 
Thanks everyone for the replies. I agree it hasn't been addressed. I searched like crazy and couldn't find anything.

Here's my sweet piece of 70's engineering. How doe the bottom piece come off? Screw? Pop? I've seen those little filters for sale on eBay.

I've also read that some people put a filter inline on the vacuum...so as the charcoal breaks down it doesn't get sucked up the line. I want to keep mine as I think it serves a purpose and costs zero performance. Besides it's the least I can do for the environment since I'm dropping a 440 into my enviro-machine. LOL

Jlcaptian24, Had several guys say to add a inline filter .Yes that happened to my 88 Ram.The charcoal bag breaks and will get sucked into the fuel bowl.Don't ask me how,always thought that the fuel vapors went into the canister and then into the intake when started.Had to remove and clean out the carb. Replaced the canister and added a mopar fuel filter into the line to catch any charcoal. After that episode I did the same to my 79 Chrysler.
That funky brown thing at the bottom is actually a inlet filter. I remember one Tech a the Dodge dealer that would replace it during any tune up.I have never checked if that filter pad is still available.Also no replacement canister is in the aftermarket for a Mopar. I have heard of using a GM one that is.

That charcoal in the carb deal is exactly the scenario I've read. I think I'm gonna keep my original and run a filter. The only other indicator (I've read) that it may be bad is your garage starts to smell like fuel. The charcoal is saturated and won't absorb fumes anymore.

Here's a link for the kitchen sponge, er....filter.

According to that link I posted it's WIX 42998 for the part number. Like 1.50 for the part....15.00 for shipping. Ebay 8 bucks delivered. That carpartsdiscount was the only one where I could link a part number to what fits. Other websites just didn't come up with anything as available.

I went through this recently with my '85 Grand Wagoneer. 'This' being charcoal making its way into the carburetor bowl. From your photo, it looks similar. So, if its internals are anything like the waggy's, there's a filter on top of the canister which has disintegrated. Also, if the venting is like the jeep's, then while running the connection to the cannister should be shut.

Anyway, here's the write up where I opened it up and replaced the filters. And probably only you guys and gals will understand the one signature line over there about a fish. :) Skim down for photos of both mine, and different variation of also used by AMC that another member posted.

And here's the charcoal inside the carburetor bowl. Couldn't figure out what it was at first, or maybe it was denial.

Mattax, you're pretty intense man. That's a bit more work than I'm willing to put into mine. I'm either going to just replace that filter....or I'm looking around for another can that will work. There seems to be a few options out there. Nothing correct for an A body, but stuff I think I can make work.

Actually, the only intense part was figuring out what was inside before I opened it, and how it was supposed to work. (An early 70s Chrysler book will be much better than the mid 80s AMC manual.) Don't let all the explanation make it look difficult. Taking it apart and putting it back together was pretty easy. Cutting the plastic weld or glue line is the only real 'trick'. Hey the other guy just hacksawed his and taped it together. The filter material and charcoal are all that yu need to buy. I didn't even buy new charcoal ('cause I forgot).

But as there's no indication that anything is wrong with yours other than a dirty filter, I wouldn't take it apart either.

Oh there's something wrong with it now....I broke it taking it apart. Ha!!
 
I don't think anyone sells a mopar correct direct replacement, but there are some GM models that I've looked at that might work if you ever wanted to replace it. The one on my 73 Duster got replaced when the car was rebuilt, but the replacement didn't have a purge line connection (it has a label, but a solid location and no hose barb) so I installed a purge valve inline with the tank.

I think I'll go this route. It's probably the GM unit you're talking about. It's only got two connections. Tank and Carb. I think it will suffice...it's the same diameter as my OEM as well, so it'll slide right into the bracket.

Great thread! There really isn't much chatter about this out there. Just bought a '72 Valiant and noticed gas dumping from this thing. Took it out, and it was completely empty inside. The charcoal had disappeared and the filter was gone, too. We're thinking the gas issue has to do with the float, but thought we'd look for a replacement for the canister while we were at it. I've seen one account of cutting the canister and filling it again (My Jeep CJ5 Page - Charcoal Canister Rebuild) but thought I'd see what was out there in case that doesn't work.

My question: There are some Jeep canisters that are the same size, shape, and have the same number of ports - can anyone think of why they wouldn't work?
 
I asked slantsixdan what canister might work for my duster and he brought up ACDelco 215-153 (edited part number to remove typo)
I called my buddy at advanced auto parts and he cross referenced it to their supplier and it came back under 40 dollars (plus tax)
I should have a part number tomorrow
