While working on completing a wire tuck on my car today I located a vacuum line that goes over the passenger fender well and under the PCM. Upon disconnecting it, I found a break in the line.

With some research I believe it is the vacuum canister line. However, I can’t seem to verify this nor can I locate any replacement vacuum lines specifically for it.

I have attached pictures of the line and the check valve it went to in hopes someone can guide me in the right direction in located and buying a new one.

Any help is appreciated!

 

I believe that's for the HVAC system.

 

Yes it is. After a lot of digging I finally found the GM part number for it. The part number is 12186372 however it’s been discontinued.

I’ll try and cross reference it and see if someone sells a replacement. If not, I’ll see if I can make a new vacuum line or repair the one I have.

As always, open to suggestions.

 

You could try contacting Hawks Motorsports and see if they have a good used one.
