Well i checked my vacuum lines and found this, i just got the car out of the shop and i told them the lines were broken right there and needed to be replaced and this is what i found. Where can i get new vacuum lines and what is the name of the connector that should be right here. Can anyone tell me what they were trying to accomplish by doing this, and can where do the vacuum lines run and i will fix it myself.
It depends. On my caprice the elbow going from the throttle body to the pipe that then goes into the solenoid that this plugs into was rotted out and cracked badly. I can't get a replacement, thank you GM for discontinuing that part! I drove it for a while with it unplugged and capped the port on the throttle body, and aside from the CEL it ran fine. Is the solenoid still there?
I dont know the size off hand. The bottom line goes into the harness and then from there I think it goes into the charcoal canister. Hopefully someone can correct me on that. The elbow from the throttle body to the plastic pipe is 2 different diameters, which is why I couldnt get a replacement. You might have better luck getting this from a yard. Make sure the port on the throttle body where it goes to in the picture is capped off as yours is setup now. If its not, that will be a huge vac leak.
The vacuum port on the TB is about a 3/8", while the vacuum port on the Evap purge valve is about 1/4". I cobbled together some pieces from my local autoparts store 'Help(TM)' aisle. They had an assortment of emission hoses and vacuum hose adapters. I found an 'S' shaped piece of emission hose that was the 3/8" diameter, and a 90-deg piece of emission hose that was the 1/4" diameter. I pulled the rubber hoses off the plastic line, and adapted the 3/8" to 1/4" using a vacuum hose reducer from the vacuum tee assortment package, and used spring-type fuel line hose clamps to secure it all together.
The whole assembly was a little long, because I didn't want to cut that plastic line, in case I found some rubber hose that was better to use, so I left the 3/8" hose a little long so things could 'snake' around a bit so nothing would kink.
