258 Vacuum line removal

I'm doing the TR ignition upgrade and bypassing the computer with the Nutter bypass. I would like to know how to get rid of these vacuum lines. I know I need the line going to the distributer and the one for the front axle connect.
If anyone could let me know what one I could remove it would be great. I my jeep idles great after I machined out the bushings by the butterflys and added a new bushing with a o-ring. I found most of my lines are either broken or disconnected anyway. Please help me remove this rats nest. P.S.- have seen it done and can't get in touch with the owner of the jeep.

Re: 258 Vacuum line removal

You will need the front axle disconect(there should be three lines), The vacuum advance on the distributor, the pcv line from the air cleaner the the back of the valve cover, the pcv line from the front of the valve cover to the carb and possibley the line going to the egr valve. It is a little round shaped thing bellow the carb that sticks out of the intake. It supposidly keeps combustion temps down by reserculating exhaust at higher rpm. The rest of it, in my opinion, is just dead weight. But before you do anything do a search on this subject, there has been a lot of threads that talks about this very thing. Check out this website www.off-road.com/jeep/tech/258bbd/index.htm, it tells you what everything does and how they work.

I need to get a girlfriend I'm getting to close to my jeep.
