Mmm who wants spaghetti?

This is a pre-rebuild and pre partial desmog photo.
I am not against the smog valves but Im pulling most of them because I doubt their functionality. I pulled the smog pump and it was full of plastic chunks.
anyways, im keeping the charcoal can because it does serve a purpose and isnt an eyesore. This question is about the small vacuum tube that was circled by a kindergartener: it originally routes to some valve. Right now its just vented out to the engine bay. Is there somewhere I can plug it back into the carb?
theoretically these are perfectly good fumes I could be burning. Or does it need to be regulated to be of benefit?

 

Wow that is kind of busy looking. All I can tell you is that on 81 to 83 Canadian emission standard 4x4 trucks that hose goes to an advancer port on the carb and my truck works just fine. I think the design of the canister may be a bit different though.

 

A level picture would help. My neck is killing me now. And instead of circling the vacuum line, trace a line along the tube. I can't see the loose vacuum line but plug it for now regardless.

What year is this? It looks like a CA model with a HAC (High Alltitude Compesator).

 

It's a 1980.
Not Canadian. The previous owner was from California but I haven't confirmed if its CA smog or not yet. I don't believe it has a HAC, I wish it did.

I'll try to put together a better set of pictures to trace the path of this hose.

 

Could you point out which advancer port yours goes to 83?

Thanks

 

By the looks of the picture it is a California model. Notice the (3) VSV's on the passenger side. From the top down view I think it's a resonator and not the HAC as it would have (3) small vacuum lines instead of the larger ones.

 

1. I think its pretty clear its not a 81-83 Canadian emissions truck due to the fact it has 300 more miles of vacuum hoses and stuff.
2. It looks like a federal US emission standard. Thought Calif models had two canisters, one for the fuel tank the other for the bowl, but could be wrong. Should be a sticker under the hood...if its still there! Might be able to glean something off the VIN plate on the drivers door jamb.
3. The 1981-83 22R and the 1979-80 20R carburettors are different so...
4. If you want to try what I suggested I think looking at your photo and an 80 FSM it will be the vacuum line that crosses over the top of the AAP and banjo fitting for the fuel line. Or try the port beside what appears to be an idle mixture adjusting screw (I thought they were plugged over on all catalyst equipped vehicles). Just make sure its on the same plane as that advancer port. I thought emission hose spaghetti models had metal vacuum lines with just short stubs of rubber hose...leads me to believe someone previous to you "modified" things!
