Here are pictures i took from my motor of vacuum lines that are unhooked. Does anybody know where theses go or have pictures showing where they go?

Pics didn't come through.

 

ill give it another try

 

It says my pictures are too big to put on so ill try to describe them.

1. Where does the emission tubing from the heater valve go?

2. Two rubber hoses on the passenger side of the throttle body. One is located to the left of the tps sensor, and the other one is between the iac valve and the tps sensor and is connected to hard a emission hose which goes into a connector below the distributor. Do these sound like they go to the charcoal canister?

 

Ther should be one vacuum line going to A/C control head, and one coming from it to the heater coolant flow control valve. There is no emissions tubing going to the heater valve in the emission sense, only vacuum.

TB Upper hose goes to right rear of valve cover breather.

Lower hard hose goes to canister.

There could be a 3-way check valve connected to the plenum, A/C control head, and vacuum reservoir (black ball located under canister and behind left, or right headlight.

 

Does anybody have pictures of these hooked up?

 

I don't use the A/C, Heater Valve, or the EGR so I can only show the the TB stuff. I high-lighted the hoses in the pictures for clarity.

 

thanks for the pictures. Does anybody else have others that they can put up?

 

Here are a few more i need help with.
1. What hose connects to the top of the purge solenoid? Also where do the electrical wires from the purge solenoid go to?

2. Where does the hard emission tubing from the purge valve go? Mine connects to the fuel tank pressure control valve but before it gets there, it goes into a T-connector. The hose that comes out of the T-connector is broken off right where it comes out.

3. What goes to the hose on the plenum that is behind the fuel pressure regulator? Is it the HVAC?

Any help would be great. Pictures would be even better.

Thanks, I printed these out the other day and they helped alot. Just a couple questions still.
1. Is the hose that goes from the top of the purge solenoid the one that goes into the throttle body or is it the one that goes underneath the throttle body?
2. Is the HVAC line the one that runs over the distributor, the wiper motor, and down the drivers inner fender? Is it also supposed to go into a wiring harness behind the motor or did somebody mess around with it?
3. Where do the electrical wires from the purge solenoid go to?
Like i said before, if somebody has a picture of these on their car it would be a big help to me. Thanks

 

Have you looked at any vacuum diagrams? There should be one on the bottom of your hood I think. It might help you out a little bit.

 

1. Mine seems to match the 90-92 diagram except for the tank pressure control valve is on the line that crosses underneath the TB to the lower port on the right side of the TB. This is the line that should go directly from the top port of the canister to the right side lower TB port.
Note: The port "A" on the underside of the TB connects to the EGR solenoid and nothing else.

2. The line that runs down the fender connects to the Vaccum reservoir (see picture) and goes nowhere from there, the other end connects to the plenum vacuum port closest to the distributor and tees to the shortest of two hard black HVAC lines in the wiring harness behind the motor via a 3-way check valve. The longer of the hard black HVAC lines goes to the heater coolant control valve.

3. The purge solenoid connector is in the same harness as for the windshield cleaner fluid pump motor.

These are the only other pictures that can help you.

 

I cant check under the hood because my emission routing decal is missing. Ive looked at diagrams but im really hoping somebody has pictures from their cars that they can show me where the hoses and wires i talked about go to.

 

Alright i got this picture to work. Where does this one go?

 

That is a 2 port vacuum check valve one port goes to the vacuum reservoir ball I've already told you about in my last post, the other port (probably facing away from the direction you took the picture) goes to the short hard black plastic HVAC line. if there's only one port then you need to put a Tee so you can connect both the ball, and the HVAC.
