i'm in the process of replacing the vacuum and electrical on my k5. its a 86 350 with a qjet and its a california vehicle. i'm trying to find out what these are, the pic1 is by the vac canister and i think it might be a vac purge assm. the other one is on the passenger side behind the carb. your help is appreciated, thanks guys.

 

the first pic (at canister) looks ok. The second pic looks like it melted, Its a temp controlled valve to the ecm that connects a port in the front of the carb to the egr valve. I can try to snap pics of the factory setup I have ('86 K5, california) but i also posted on an earlier thread that may help too...
