91 yj charcoal canister replacement

So I've been looking to replace my vapor canister aka charcoal canister. I've found the cp3045 canister and the cp1061 only issue is I'm too late and there all sold out.

Has anyone found one similar or found a canister and retro fitted it to the yj? I have a 4.0l yj if that matters

I don't know if it matters between the 4.2 and the 4.0. Here's a thread with some info, somewhere along the way there's a catalog link as well..... http://www.jeepforum.com/forum/f12/v...hange-2492001/

All part numbers listed are no longer available. Not sure which kind is compatible anymore

That's odd...

The CP1004 was not a direct replacement, it's a bigger diameter but works nonetheless. Again, I don't know if the 4.0 and the 4.2 are the same, I would assume you may have to cap off the carb vent port.

More than twice what I paid though..

Otherwise you may have to search the catalog for one that closely matches yours.

Did you try the search tool that I posted in that other thread?
http://ecatalog.smpcorp.com/STD/#/searchparts

It's a little clunky to use. But go to that page, and on the left side, bottom of the list, use the "Product Category (Part Type) Search". Scroll down and select Fuel Vapor Canister. Don't select any specific year or model or any of the other items. Just hit Search, and it will show you a list of ALL of the canisters. There is a ton of them, and you just have to pick through them to find one that you think will work, as far as size, number of ports, it needs a built-in purge valve, etc. I wanted one as close to original size, and cylindrical shape, fit in my mount, and so forth. But the more of these that go out of production, the less selective we can be. Most of them are rectangle instead of cylindrical, and I ignored all of those, but in reality many of them will probably work. You just have to figure out how to mount it, and hopefully your smog check, if any, is not too much like CA.

Searching briefly, I think this one might work. But you need to decide that on your own. I only like to waste my own money, not yours

Be careful with the used ones. I got burned on that. Mostly what goes wrong with these is the diaphragm in the purge valve gets a hole in it. And resellers don't know how, or don't care, to test them. The charcoal itself never wears out, and the base filter is still available and very cheap.

I did not buy the one I linked to above. The one I bought is now obsolete.

But yeah, I think most all of the cylindrical ones are open on the bottom. There is some kind of screen or grille that holds a filter in place. They are not sealed canisters. The charcoal just absorbs volatile vapors, and then gives them back when the vacuum turns on and sucks fresh air upward through the charcoal.

The one I linked vents on the bottom like the factory, I think most of them do.

I'll dig. The cp3045 doesn't which mean the mushroom cap I could take off and extend all the way to where my diff breather and transfercase breather are located

I will keep digging but does this look like it could work? I assume the bottom one is a vent nipple and looks like it has a diaphragm. Would it matter which way it was positioned? Hoping to mount up and down like factory

I apologize if I keep posting ideas. This one looks like 3 nipples ontop and one at a 45 degree on the bottom. I guess I know I'm looking for 4 nipples one being a vent so I can eliminate any water getting inside. Basing this idea of the cp 3045 which is no longer avaiable.

May not help but I used cp3034 in my 87 2.5. The 87-90 2.5 used the same canister as the 4.2 but the hoses went different places. The cp3034 is a little smaller and the ports are placed opposite. I've had it in installed for like a year or so with no problems. Paid $100 on eBay. Just saw one for $148. No they are not gold plated.
