Ripping Out the Vacuum Lines

Now that the Mighty Eight (1985 CJ-8, 258, TF999, Carter BBD w/ Nutter Bypass [no stepper motor]) (thanks hobbs) is getting cranky and I seem to spend a half a day every week tracing out vacuum lines I just want to RIP THEM OUT AND START OVER.

The 1975 CJ-5 that I used to own had a Carter BBD with none of this emission crap. I live in a non-emission testing state and because of the Good Old Boy Network probably never will. Also, this is not a daily driver, so I am not going to be adding alot of NOx and SOx to the air. So getting rid of the emissions is not a problem.

I am thinking of just leaving the EGR and the vapor canister and removing everything else. Since I have the TF-999 auto transmission, I probably need to leave the Idle/Decel Vacuum Switch which controls the Sol-Vac and the Purge Signal for the vapor canister. I think everything else has to go.

Any suggestions would be helpful.

Re: Ripping Out the Vacuum Lines

Hey,
I just did a motorcraft 2100 carb swap on my 87 YJ. The only vacuum lines that I left was one to the PVC valve, one to the vacuum canister. Teed off of the canister I have the front axle disconnect which you will not have. There is one I have left for a heater(I think-little one on the back of the intake). Do a search on here of "carb swap". There's a couple replies that helped me out a lot.
Also I have a 5-speed so that will make a difference. Just give yourself plenty of downtime and go though it all. You're not going to hurt anything.
If you're unsure of yourself, mark the lines as you take them off in case you remove something that you actually need. Good luck.
