Im order for you to legally pass smog, the oem type of cannister is required. There is another cannister that will work quite well, possibly dirty it up a bit and hope that the smog guy doesn't catch it. I can get you that p/n if you want it. Another option would be a junkyard like J & W Auto Wrecking in Lucerne Valley-They have a website.

Hell yes, send that part number over please. I had a feeling this thing would not smog without it. Thanks.

This link will give you the p/n and tell you how to hook it up:My Tech How-To for the Carbon Vapor Canister - International Full Size Jeep Association
I hope this will work for your older CJ, its the best thing that I can come up with.

Blue and rust colored.
After gettng my new canister in and hastily drilling the port as specified in the link, I'm not sure it's supposed to actually be drilled.

This is the one I got. The port on the left side (looking at the port openings) seemed to be open and not need to be drilled, and the one on the left with the "X" was blocked.
I kind of want to order a new one and test it. I would think the tank and carb vent ports are "blocked" when there is no vaccum on the vac port on purpose, so the gas doesn't evaporate, and it is vented when the engine is running, no? If you order a new canister you should attach some clean line to it and see if both those side vents are open when there is vaccum on the top port.
Torxhead, you know everything just tell me it is okay and I should let the smart people do the thinking.

When I first got mine I did a vacumn test and found out just how it works, It was a few years ago though. The two outer ports as I recall, the one for the 1/4" hose is for the fuel tank vent and it is open all the time just as is the setup on the oem cannister. If you drill out the other port it will also be open all the time, again as the oem setup is. I did not drill out the larger port as I have fuel injection and do not need a vent here. I did check it and it is plugged off, btw. The remaining ported vacumn line goes to the cto valve and the remaining pcv hose goes into a union of the carb pcv port and the pcv itself. I did drill out the smaller gas tank vent port, I don't think it was needed though.

FAILED CA SMOG TEST (evap). I have the same canister on my 1984 CJ8 with a 1996 4.0L fuel injected. One of the ports is blocked. Am I to understand that I should NOT drill it out because I have fuel injection? Also, I'm not clear what hose the PCV is-can you explain further? The line going to the pcv currently comes directly off the intake manifold. I also have a line connecting to the air intake duct off the throttle body(?)

I followed the instructions and did do the drilling out, followed by passing smog.
I did once confer with a smog checker guy and was informed that to pass smog I would need the oem canister. So I got away with it, once anyway. Another time I went in for a smog check and forgot to remove the breather cap and go busted. I did carry the correct cap, replaced it, and passed.

I noticed your in Texas so you don't need to worry about passing emissions. On vehicles that old they don't require it in TX. No worries.
