vacume lines after nutter bypass

ok so i did the nutter and i want to rip all those nasty usless lines out. but i dont know what ones i need and idk where to cap them off at. so a little insight maybe some pics would be great. and also i dont get a whole lot of pull on the distributer cap vac line. is that a problem?

Heres something to look at http://www.jeepforum.com/forum/f12/vac-line-clean-up-post-nutter-post-weber-well-now-677814/

also.. what kind of carb you have? did you move your vac line that goes from Dist to carb to the other port?

Hold on there now just a minute!

Some of that stuff is important.

The charcoal canister & all the lines connected to it.
The CTO switch & it's lines.
The EGR
The intake manifold heater.
The manifold vacuum going through the firewall, is for the cabin heater/AC

There are more items too, you really need to know & understand any wires or vac lines you are going to cut out.

For instance, the side of the battery tray has two relays & a plastic box with resistors in it. Cut those & you won't have electric choke, intake heater,(important) & the box is for the sol-vac & the rear window defroster.

Whatever you do, don't cut the resistance wire in the engine compartment loom.

Much of that emissions crap can come out, but you need to research it till you are positive.

If the distributor vacuum line is connected to a timed port like it should be, then it's not gonna pull much at idle. Connect a gauge to it & increase the rpms to see if it gets more vacuum.

Edit; Tompatt's links are good!

I would suggest leaving the intake heater though, it really helps on a cold morning.

ok thanks for the quick response. i am running the carter pos. and yes i have moved the lines around using the t split. and thats y i came here cuz i know i can pull out some of the usless wireing but i dont know which ones i should and shouldnt touch. but it just dosnt seem to have any affect on the idle if i pull the vac. line off from the dis cap and leave it open. i would think it might change something. i may be wrong. but thats y i come to jf
