So some of my emission systems don't work because either they don't work properly or they are dead because the computer no longer controls them because of the nutter bypass or for both reasons.

Because of this I don't need all those vac lines BUT I don't want to remove anything to keep it looking stock and for emission inspection appearances.

So, want I want to do is replace all the vac hoses but then plug up the ones that I don't need to eliminate sources of vac leaks in either the lines or old emissions equipment. Obviously I want to plug the lines as closest as i can to the carb without killing the vac lines i need to keep.

My question is any thoughts on what to plug the lines with but have it still look like they are connected?

My best thought is aluminum rod (slightly bigger than the ID (3/16 rod inside a 5/32 vac hose) cut to about 1 inch long and put inside the line. I don't think a inspector could tell the line was plugged by looking at it. I also don't think there is anyway the vac would be strong enough to suck it up the line and damage something.

Must be a silly question to some I know!
 
To someone who has to deal with these dumb smog laws I think you have a good idea. I think as long as it passes the tail pipe test i shouldn't mater whats under the hood.
 
Sounds good to me, anything cheap to plug the lines like wood dowls aluminum plastic should work

BB's do a great job of blocking v'lines. :D
Tell me about SMOG stuff:rolleyes:-I have to pass a visual and tail pipe test every 2 yrs here in PRK.
Just finding some of the vacuum switchs is a large PITA.

Ball bearings, BB's, anything round will be much easier to get in the hose.
 
Lumpy beat me by a minute.... ;)
 
I heard about using BB's but I don't want to suck a BB into my carb! Thought a inch long rod would be much much hard to suck through the line over the years. But I guess the BB will never be smaller than the ID of the line you are hooking the hose up to so I guess a BB will work just as well.

While we are on the subject of hoses, any thoughts on using something other than regular vac hoses like silicone, etc? Or is that overkill and just use a good brand regular rubber hose?
 
Well I tried to put a 3/16 steel rod I got from the local hardware store into a 5/32 ID vac hose line. Was kinda tight but wasn't difficult to put about 1 inch section into it. Course I want it to be tight so no vac leak! Looked at it and you can't even tell it's in there unless you try to bend that section.

But I think I need to find an aluminum or stainless steel rod. No corrosion/rust flakes to worry about going into the carb.

I also need to file the ends smooth when I cut it so no jagged edges to cut the vac tubing and make a leak.

Pretty sure this is the solution. Thanks for everyone's input.
 
Well, after you go for emissions testing post back and tell us how it went. For a little info on how the later CJ emission system works check this site:Jeep Adventures Under the Hood.
I once passed with a Nutter bypass done but I am not sure how.
 
Well I already passed emissions without doing anything after I bought it other than cleaning the idle jets because it would stall at a stop and adjusted the idle screws. Not sure because of the age if they just do a visual or do actual testing where I live. I didn't bring it to a place where you actually can see them do the inspection/tests. They may have done no testing or looked at anything. I didn't ask and kept my mouth shut before I gave them the keys! LOL I also hid some disconnected electrical lines like the ones that come from the computer. ;)

Next time I'll bring it to a place where I can see what they do.

My vehicle has had the nutter bypass done on it when I bought it.

Appreciate the info link but I already knew about it :)

Fantastic info! By far the best I have seen on the internet other than the FSM. I have it all printed out and in my Jeep binder and in case those webpages are gone one day! It has helped me tons seeing what is what and how everything works. Again, appreciate the info.

It also depends how knowledgeable the person is on the visual inspection.
I've had a couple 'techs' that I swear had never really seen a carburetor before. :rolleyes:
One tried to tell me my MSD ign was not allowed because it wasn't OEM. Never mind the fact it carried a 50 state EO that has C.A.R.B. approval, and said such on the red 'box'. :eek:
Here's the funny part-My Jeep is older than these so called 'experts' were. :laugh:
 
I have had the same guy do my all my vehicles for over 30 years. If doesn't pass he will help me get it to do so, even get a free retest. I figure its best to work with these guys than against them.
 
I had been using this one shop in Lancaster for 20+ years. The owner who was the SMOG tech died in a MC crash. Heck of a nice guy and he did the same for me as your guy does.

Tried another shop and found those 2 idiots. :eek:
The place I have been using the last couple of years looks very promising.

Around hear they all are State sites full of dumb asses.
 
Feel sorry for you California guys on emissions issues. :(
 
Since I converted to T.B.I. smog tests are no sweat to pass, just a pita and somewhat expensive. The day might come soon when vehicles in all states will require an inspection and test every two years.

Let's hope it never gets like californication. Sounds like they now want to ban just about everything except wind. That is great if you have a sailboat. I love sailboats. I sailed a boat everyday to high school. But I don't want that for my jeep.

Oh come on! Just weld a mast on, hook up a boom, run a little rigging, and you are good to go! How many knots you looking to get out of your rig?

I'd like to ask this question again: While we are on the subject of hoses, any thoughts on using something other than regular vac hoses like silicone, etc? Or is that overkill and just use a good brand regular rubber vac hose?

No 30+ year old vehicle should be required to have inspection every 2 years.
Remember that our Ca model CJ's are held to a 'tighter' SMOG standard now than when first sold. All it does is suck $$$$ from us for that AH's, train to no where project.
When Reagan was run'n the state-It WAS a great place-NOT now....:mad::mad:

I run std hose and use a small tie-wrap to keep them in place and from leaking.
