Emissions Removal Help **pics inside**

**NEW QUESTION**

I'm just about to wrap things up here, but I have a couple last questions. I need to find a vacuum source for I believe the one on the left. The other one is going nowhere because what it ran to was removed. But the other one needs vacuum and I'm not sure where to connect the other.

Where does this go?

I am thinking that maybe it runs to the throttle body like so?

If it doesn't, where do I hook the vacuum line on the throttle body up to?

I have began putting my intake manifold back on today after doing some emissions removal. I removed the EGR and cleaned my IAC and did a couple other things. Now I need some help though. There are a few things that I am unsure of.

First, I need to know what these two are and wether or not I can remove them? I want to do away with most of the vacuum lines and there are quite a few going to these, but I don't know what they are for.

Next question, there is a line running down beside my fuel line and I can't remember where it went to.

The last thing I'm not sure what to do with is this

I know where it was, but what is it? Do I need to keep it?

Thanks.

don't do it. its a hassle to pull everything off and have your car run right. If you decide to pull everything, have a friend help you hook up all the necessary vacuum hoses to the proper ports. Use a fsm to help you with hose location... pause....

looks like a fuel return. This hose hooks up the tube coming from the FPR side of rail.

Photo3
The purge/vent valve of the charcoal canister. keep it unless you want fuel and unburnt gas vapor in your engine compartment.

Thank you for your help. The line is not a fuel return line however, all fuel lines are hooked up. I will start doing some reading in the FSM.


**edit** line just runs to the purge control valve that is pictured in pic 3. I think I have everything all figured out now that I looked at the diagram in the FSM. Really I should have just done that is the first place, it would have answered all my questions haha. Thank you again for your help.

I have a new question and didn't want to bother making another thread. Details and pictures are in the first post.

You can plug the nipple under the throttle body.
The nipple on the intake goes to one of the lines that run under the throttle body, you can plug that as well.
If you do not heave a heater core, you can remove all of the coolant lines.
Make sure to hook up one of the remaining vacuums to the fuel pressure regulator.

I still need vacuum to one of the circled nippled, I think its the left one, it branches off and goes to something tied into it that that needs vacuum. The other end is plugged.

I still have my heater core so I kept the coolant lines. Those are all hooked backed up.

I've seen the pics that you posted before too. There for an S13 manifold and from what I see, I think there are some difference between mine and that one.

Can I block the nipple under the TB and then run the vac line off the intake to the nipple I need vacuum on?


**EDIT

**GOT IT FIGURED OUT.

The only vac lines you need are;

Brake booster
FPR
IACV
PCV

Those are self explanitory. All other lines can be capped off/removed, with 0 side effects what so ever- as long as you have an <OBD1 S14.

The vac gallery under the lower IM can be capped off. Once you remove the EGR setup (easily done with engine/IM in the car -15 minutes tops) you can access the rear EGR/solenoid, remove that with associated vac lines. Once the solenoid is removed, there will be only 1 nipple on the lower vac gallery that will pull vac, because the larger 5/16th line is connected to the middle of the lower IM plenum.

Pic 1. 2 circled connect to the EGR solenoid. one to the left uncircled needs to be capped off.

Pic 2, cap off. Runs to EGR/evap solenoid

Pic 3. No, cap

Last 2 pics look like evap.


You dont need evap, trace the vent line, and clip it down towards the center of the car. Slightly bend it to prevent moisture.

Egr, get the proper m24x1.5 plugs for the exhaust mani, and get an $8 ebay block off plate for the IM. Install proper resistors.

Remove EGR/EVap solenoid, lines and subharness

Hell even remove the intake-valve cover restrictor, its only to help blowbya nd increase negative pressure in the crank- bad if your PCV valve is clogged.
