Hi I have a 1984 Chevy K5 Blazer with a 350. I have been trying to get this beast to pass Colorado emissions. I do believe that this is the part I need to replace in order to achieve that goal. So my question, is does any one know which canisters I can use in my blazer. The one that was installed has several broken vents and has the stamp 17061005BT. I have been searching for this and cant seem to find it anywhere, besides one web site that is not reputable due to lots of bad reviews. If anyone knows where to find this, or knows of a different model that I can use that would be great.

Thanks for your time,
Darkodan
 
Unfortunately I don't see one listed at rockauto. I found one here based on the number you gave: https://www.gmpartsstore.com/oem-parts/gm-vapor-canister-17061005 Likely that's the correct part, but I'd still want to confirm before shelling out the money. Could have been swapped in, etc. Since you have to pass emissions, you don't want the wrong parts.

You can verify the right part number for your vehicle with the parts manual found here: http://67-72chevytrucks.com/vboard/showpost.php?p=5621043&postcount=1

There were a bunch of the vapor canisters out there for the same year trucks, so you will need to make sure you get the right one obviously.
 
That's the one I found but when I looked up that website for reviews people were very unhappy I'll try that link and I'll keep looking the one at the gmpartsstore is the exact one I had in the truck thanks I'll keep looking
 
I got lucky by finding a charcoal canister on an 85 Suburban at the junk yard a couple years ago.
 
Iirc, isn't there a filter in them things? Wonder if it's clogged...
Think I read that some years ago...put in my memory file of useless info lol
 
Never mind...found this thread.

EVAP Canister Filter Replacement

How do you replace an EVAP canister filter on a 73 to 87 (1988 to 1991 R/V) GM truck? I did a search on this site and Google, but I cannot find anything on it.

I'm wondering if the part number has been superceded by chance. I can't find the interchange listings that acdelco.com used to have. They don't seem to list one for the 1984 K5, but I did find one for an '86 here (which are supposed to be the same, but I question that): https://www.autozone.com/engine-man...r/p/acdelco-vapor-canister-215-151/616162_0_0

yea i was thinking i could use some fiberglass matt and an epoxy to fix the broken nozzles and just replace the filters but i dont want to have my emissions rejected because they think im trying to modify any parts
 
I tried installing a new canister filter in my truck thinking I would get away cheap, and it was a total failure. Trying cut out and seal up the bottom of the canister with epoxy like the in the instructions will not work. You will end up have a massive vacuum leak. I just bit the bullet and bought a new canister. It was expensive (about $130), but it worked. I needed one because a couple of the vacuum ports where cracked, and vacuum leaking like crazy.

Why did it fail emissions?

I would have to find the emissions test results I had it posted in here about a year ago thinking it was the carburetor i fixed that and re did all the vacuum lines new gas tank new exhaust and when doing the vacuum lines I noticed the canister was broken so I think that is it but the tests were running really highand it's running rich

Any auto parts store should be able to get one. I got mine from an auto parts store. I think all the carbureted canisters are the same, and all the TBI ones are the same.

Charcoal cannister shouldn't have any effect on emissions as long as the tank isn't having pressure issues and there is no vacuum leak from a bad/broken/disconnected cannister/lines/switches, etc.

It's sole job is to keep evaporative emissions (gas vapors) from escaping to atmosphere. The amount of change to air\fuel mixture it would make on a carbed setup is minimal, when talking proper operation.

My guess the EVAP canister failed a visual inspection. Since a charcoal canister is connected to a vacuum source at the carb why would there not be a vacuum leak if the system was not sealed completely? Depending on how far down the line the vacuum leak was in the EVAP system effect on emissions would be minimal. If the ported vacuum port on the carb that the EVAP system connects to was wide open then that could definitly effect emissions.

I figured if you know it's broken you'd know to plug the leak? Just what I would do, but if the OP hasn't done that then yep, it's gonna run bad.

The link I posted stated he passed visual.
 
I have a canister in a 1986 3/4 ton Silverado pick up that if it helps, I would send to you for the cost of shipping. I just got the truck, will be taking some parts off for my K5. Then probably junking it. The point being, I know nothing about the actual status of the canister other than it’s there. Good luck.
