Do you have photos of the actual hose routing from the canister to where they connect to? My 88 gta 5.7tpi canister with 2 connectors coming from it. One going into the control valve, with the control valve with 2 connectors coming from the side. one connector goes to a thin hard black line which I guess goes to fuel tank. Where does the other connector go to?
The schematic shows a hose connector coming from the bottom of the control valve with hose going back into the hose coming from canister to control valve. My control valve has no hose connector under it. Both connectors are on the top on side pointing out.
Also what size is the other hose coming from canister to throttle body? Is the end coming from canister smaller then the other end going to throttle body?
I am asking cause I disconnected them a long time ago, misplaced photos I took so now I can't figure out how they go. Yes that means I SNAFU'd. I have photos of the canister and connector if some one needs to see them.
Unless I can find another 5.7 tpi gta here in san antonio to compare to, then I would be ok.
Any help out there? Thank you

I just lost a long paragraph with parts #'s and description and now you are offline. I'll keep this one short. I have a 1989 IROC-Z w/ TPI and a 5.7L. The car has Edelbrock Aluminum Heads #60859 and Hedman headers. I need head, intake, and Exhaust gaskets. I've narrowed it down to a few choices but I am still unsure as some of the items I need are discontinued. Here is what I have found: cyl. head: Edelbrock #7310 or Fel-Pro #HS 7733PT-15(head gasket set w/Perma-Torque) or gm#-10159409. Intake manifold: Fel-Pro #MS930351. Please feel free to recommend the correct gaskets. also any opinions on the Perma-Torque or MLS or composite gaskets for Aluminum heads w/ a cast iron block. Are the gaskets for the 5.7L and the 5.0L the same? I'm going to send this before I lose it. The car has a stock intake manifold. Thanks for any help.
milhouse89, to whom are you directing the message to? The thread is about vacuum lines for a 5.7l. Not sure if you will get your answer to your gasket questions on this thread but hopefully someone will come thru. good luck

Yea, I thought I was doing a private msg to eseibel67 but I am no computer expert. I've tried 4 times now and I am getting really tired. My last attempt was an e-mail and I don't think he got that because I'm not sure if this site has my e-mail. I wanted to e-mail because I need this done yesterday. I might try a pm. If you want to do me a solid send the above paragraph with all the gasket part #'s to eseibel67. Thanks man.
84 Trans Am 5.0L "H" auto.
I'm going to a mechanical advance distributor and M4ME quadrajet carb.
I'm removing the air pump, air management, EFE & EGR. But I am keeping the charcoal canister with its CCV and Purge TVS. Do you have any export (non-CCC) diagrams?
Attached is what I came up with - 2 different versions for connecting the CCV. My car's original diagram is XJW.
Edit: A big thanks to T.L. for double-checking this M4ME diagram. There was an error which is corrected now.

Reason: Cleaned background of diagram.
I just collected ALL vacuum lines from 82 - 92 TG F-Bodies!!!! If anyone needs one, search below on this 1st page. Models covered with vacuum lines are:
From what i can tell the 82 never came from the factory with a 350 either. If its a transplant, go find the year of the motor itself, then look for the diagrams.
or look for the 82 with the 5.0 - and match the hosing up from there.
Good morning, First of all, I am sure that I speak for all of us, Thanks for your hard work. I printed out what I need. It'll help me to finish my 305/350 swap. I was wondering if you could find it in your heart to post sensor diagrams for 1986 5.0L 305 TPI and 1990 5.7L 350 TPI. I would like to finish up the wiring re-route within this next week and get the rest of the mechanical done. I haven't heard my 86 IROC run for a year. I am still running all the smog and stuff as well to keep it looking stock. "Sofakingdom" helped me immensely on my engine mechanicals, so I have the .502 grind cam and all the comp cam goodies on it that he prescribed. Also have a nice performance cat that is a 1/4 of the size of the stock one, 3" the rest of the way back to a flow master system.
