Could some one give me a instructions on removing smog control system for my 1980 cj5 (258 engine). The biggest question is what to do with all of the tubes that are connected to the canister. Do I just plug them all.

Thanks tncj5

/wwwthreads_images/icons/frown.gif I just checked with my moonguy-in-chief/wwwthreads_images/icons/wink.gifof smog issues and his recommendation is that you DON'T disconnect anything. The carb bowl vent line is good for you, and the tank vent line keeps from filling your garage full of gasoline fumes after you park your Jeep, the vacuum purge line is for taking the fumes out of the cannister, and the vacuum signal line tells it when to go. So you see, it is all GOOD for you AND your Jeep, and in no way retards performance. Moonguy/wwwthreads_images/icons/wink.gif DID recommend, however a clear gasoline filter in the CARB BOWL VENT LINE to prevent charcoal intrusion into the carb bowl should you have some sort of mishap. It's a darn good idea, and well worth a cheap fuel filter./wwwthreads_images/icons/smile.gif Moonguy/wwwthreads_images/icons/wink.gif also said that if you want to get really dumb and disconnect everything that you should fit a filter on the line that goes to the tank and keep it up high. Plug the vacuum signal and the vacuum purge line, and put a filter on the carb bowl vent line and keep IT high also. And one more thing.......check your garage vents and be sure that they are open since your Jeep will be coughing up gas fumes, they need to get outa the garage before they reach the flame in the hot water heater./wwwthreads_images/icons/crazy.gif

I never believe any statistics unless my moonguys /wwwthreads_images/icons/crazy.gif/wwwthreads_images/icons/wink.gif made 'em up themselves.
