That's your EGR with a vacuum hose attached to the 4 port emission block below.
The vacuum hose is hard to find and why more than likely someone use a short piece of rubber hose to couple the 2 ends together.
The original plastic vacuum line has a bulge/bell at the end that fits inside the rubber connectors to keep it from pulling out of the rubber connector.

If you don't have your smog equipment from the smog pump back then you can just cap/plug the other vacuum off leaving the EGR line still hooked up to a vacuum source.

Thanks for the info! Very detailed. Is there anyway to know which line does what? One of mine are just cut off and I am not even sure that the ones that are hooked up are hooked up to the right things. I no longer have a smog pump. I have a shorter belt and am without it. The one cut off, should i clamp the end?

Thanks for your help!

Mike

The diagram below will show where al the vacuum line go.
If you're not using a vacuum line then plug it off at the connector with silicon so that you don't have a vacuum leak.

Get some carb cleaner. Get some vacuum line.


Clean the crap outta the motor so you know what you are looking at and to see the condition of things. Start checking for vacuum leaks. Cracked hoses, intake manifold leaks sometimes, stuck EGR valve will be a vacuum leak......they are such sneaky bastards.

You have been a great help. Any chance you have 5 more minutes for me? Mine is a mess. What should I do here?!

I do not have a smog pump anymore or cats.

And is it possible that I don't have a air diverter and air bypass valve? Where and what? Haha. I obviously bought this used and fixed a lot but this has got me stuck.

I ordered this: http://www.ebay.com/itm/321391412666...%3AMEBIDX%3AIT

I believe they are all different diameters so they will only go to the same port so that should help you out.you can go to any parts store and get hose to fit.

Your Air Diverter and Air Bypass will be on a formed rubber hose coming out of the back of the smog pump, and my guess is that you don't have them.
You can seal all the vacuum lines that are not in use, what do the long vacuum line go to ?

the long one is going to the back of the intake mainifold. red wire coming in and black wire coming out.

the middle one is hooked to the EGR which looks wrong when compairing to the diagram, I ordered a used new set from the ebay link above. maybe to start over.

That makes since what the long vacuum line is doing and as far as the EGR vacuum line not being plugged into the vacuum port like the diagram that doesn't matter as long as you have vacuum to that port.

If you don't have the smog equipment you can eliminate all the vacuum lines and that 4 port rubber connector, all you need is a vacuum line from the EGR to the vacuum tube at the back of the upper intake.

Does the fuel preassure regulator have to be hooked up from the intake? My vaccum line to the regulator is coming from else where.

As long as the vacuum source is constant you're good to go.
