Need some pics guys....

I did a search but to no avail...

If someone would be kind enough to take some pics of their TBI vapor canister I would really appreciate it. My vacuum hose sticker on the core support is hard to read since it's all gummed up. I have a rough idea of where my purge hose connects but I'd like to be 100%.

Facing the truck, on the right side of the canister, I have a round doo-hickey with 2 vacuum ports. The bottom one is fixed and has PCV marked on it but the top one spins. I believe the top port is for my purge hose but I need to be sure so that's where the pics come in.

Thank you for any help.

I don't have pics but the round do hickey , I believe thats the vacuum canister for the cruise control/heat controls. Its used for a reserve when you do not have ideal vacuum from the engine.

The only trucks with that extra valve (so three fittings) on the evap canister, were "high altitude" setups, as the service manual spells it out anyway.

More, just for the heck of it http://coloradok5.com/forums/showthread.php?t=303909&highlight=evap+altitude

Thank you 535, those pics helped a lot! I've been noticing that my vacuum lines were not looking right after looking at them closely this morning. About 3 years ago, I hooked up my vapor canister and left it. I was looking at the lines today and a light bulb came on and I realized that I hooked up the purge line to the PCV port on the canister.

I've been fighting a surging idle for about roughly the same amount of time, and it's been a total mystery. I'm hoping that it was just that I had that ported vacuum purge line hooked up wrong causing my idle issues. If not, well it's back to the drawing board.

It's amazing how blind a person can become when a boo boo is staring them right in the face.

I have a pic of my 88's Vacuum Hose Routing sticker:

I don't think it's for high altitude though.

No, that's a little different than mine but thank you none the less.
