I'm looking for a diagram for the vacuum lines for my 01 montana. I have a p0446 code and I took it to a shop to get it on the lift to check the evap canister and saw that in the rear driver side corner of the van there was a couple lines on a T that were disconnected. Is the evap canister in the rear driver side of the van?

What your probably seeing is the air compressor and lines for the self leveling rear air shocks. Perhaps someone in the past had the shocks converted over to regular shocks and disconnected the compressor/airlines.
Where is the evap can at? Thanks for the help. I saw some lines that went to the air shocks disconnected and they were the hard plastic type lines then I found this other set that was the soft rubber type. What should I look at for the p0446 code? Could the gas cap be something to try replacing?

My van through a code about a year ago and my mechanic recommended the gas cap first,and he also said to by oem and I did and knock on wood a year later and 20k miles and no cel. You can go to gmpartsdirect.com and look up ur van in thr parts diagram and sometimes they will show you a parts diagram. Hope this helps. Report back what the fix was if you ever figure it out and by all means keep asking questions, there are alot of good people here that will help.

Hi
Several of vacuum diagrams

The lines I saw loose were part of the rear air shocks. I had time today to go check it out and it still has air shocks installed. I have the hose to repair the lines I found but I found another that was connected above the compressor for the air shocks that was the smaller plastic hose. There were 3 lines. One that came off of the air shocks compressor and 1 that went the the driver side shock and one that went to the passenger shock. What had happened was that one of the plastic lines broke where the 3 lines come together at the factory tee. Since it's plastic I cant just cut and slip it back on. Could I make a new tee out of rubber hose and a plastic tee and clip the lines off of the factory connection?
This is the connection I'm questioning. you can see where the 3rd line had broken off.
