I was replacing badly crumbling vacuum hoses today. I was feeling arround for the one labeled pcv in picture and it just snapped. I hadn't even started trying to remove the hose yet. I think it must have been brittle or even cracked already. Now for the question. How. Much trouble am I in? I know I need to replace it before emissions in Feb. jeep seems to be idling fine. If I just tape over the hole in canister and cap the "T" coming off PCV can I drive it till I can afford new canister? Thank you in advance.

The line labeled "PCV" is the line that purges the stored vapors to the carb/intake by teeing into the PCV system. You can plug the line and plug the canister, but the canister won't be able to vent and eventually will get filled up with condensed gas vapors (liquid gasoline). One fix for the broken port would be to epoxy it back on. JB Weld would likely do the trick, just make sure to thoroughly clean any grease/oil/dirt off the area that you need to fix, and be sure not to epoxy over the opening of the port.

As far as replacement canisters go, the factory canister is no longer made for the 4.2L. Just look up an Emissions vapor canister for a 1991-1995 4.0L YJ. (STANDARD MOTOR PRODUCTS Part# CP3045; Mopar Part# 53030500). I got mine from Rockauto.com. You may have to squeeze it into the canister bracket, but you shouldn't need to mod anything else other than drill open the plugged port to use for the carb bowl vent.

Ok so if I order that one from rock auto is that all that I need or do I need to acquire the charcoal for inside it or and or filter ?

I don't think I will even have to drill that port for the carb bowl vent. I don't think my mc2100 has a bowl vent?

If no bowl vent on your carb, then no need for any modification to the canister. It'll just be a plug and play swap. I found the 4.0 canister to fit a bit tighter than the stock one, but other than that it'll do the same job.

The canister is a complete unit ready to install.

Thank you so much! You helped me immensely.
