Sure. No problem. All that is underthere is a T connector. The middle tube on the connector fits over the TB nipple and the outer ends go to the canister and the EGR Solenoid. But no problem. When I get out of work, I'll post up a picture.

Any chance on taking that pic of the line that runs under the throttle body (and behind the alternator) over to the charcoal cannister?

Thank you so much for taking them and your time. I didnt realize it went way back there to that. I thought it went just to the throttle body.

No problem man. That part that the far end of the hose connects to is called the EGR Solenoid.

Go to page 1 and look for your diagram. Itll probably be marked as a 305 or 350.

Re: Vacuum Lines Diagrams!!! I GOT THEM ALL!!!!!

It was with the pieces when I got car and didn't know where it went,
A repair manual shows it but not what all it connects to
The side tees into throttle body then the little end heads to toward back of engine and bigger connection goes toward front but I do not know what they actually connect to . The manual show pic to disconnect it when removing throttle body, the vacuum diagrams don't even mention it

Re: Vacuum Lines Diagrams!!! I GOT THEM ALL!!!!!

I think that's a check valve. The only thing the I have on my 86 IROC is a T, which connects to the EVAP, to the throttlebody, to the EGR solenoid.

Do you have a diagram for the vacuum line for the heater control valve in a 1990 IROC Z 5.7 liter?
I probably do. I have to look through my GM Service Manual and of through the digital service manual.

The back manifold vacuum port on the passengers side plenum is the hvac vacuum. Vacuum goes to your mode selector in the dash and in heat mode vacuum goes to the heater control valve allowing the valve to open and coolant to flow through the heater core.

I need a diagram for a 1988 5.7 TPI. The set up was totally disassembled when I bought it.
Thanks

Re: Vacuum Lines Diagrams!!! I GOT THEM ALL!!!!!

I am interested. I also would like a wiring diagram (I reviewed my manual, but not complete or accurate). Mine is a 1985 Firebird Trans Am, 5.0 TPI auto trans.

Just editing my post, saw that you posted them all here. Thanks!

Thanks,

Ron
