charcoal canister

Is it absolutely necessary to have a canister?? Im putting my 77 body ona an 82 frame that i purchased partially finished. AMC 360 with 670 holley TA . my old jeep just had the line from the tank crimped and the rest of the lines removed. Ran fine. what are the pitfalls of not using this canister,and what would be the proper way to eliminate it if I wanted to?

All it takes is time and money

The canister is simply a vent for the fuel tank, and the carb bowl with certain carbs.

Without it, you and your garage will likely smell like fuel after running your CJ.

The canister doesn't affect performance in any way, so I don't see any reason not to run one.

Canister good. Vents your gas tank. No performance penalty, other than lugging it around with the Jeep. Minimal maintenance.

Lots of old threads about this if you search.

If you remove it, you need a vented gas cap. Gas vapors will vent through the gas cap, like they did before the 60s. Gas will leak out of the gas cap on severe uphills - that's unavoidable with no vapor recovery (canister). You could have leakage at the cap from slosh at other times.

Thanks for the input. its just that the bracket to hold the can is toast and of course the plumbing. while easy enough ,its just "more" . but I can see the value in having one thanks to your replies.
