Vacuum Issue
 

Hi..

A couple weeks ago I noticed a significant reduction in power when merging onto the highway. It still ran well enough, no missing, no CEL. Eventually the half power icon came up, but still no CEL. After inspect the car I realized that the vacuum line between turbo and vacuum tank (number 3 on diagram) was not connected and very fragile, so I have order a new one but when I was connecting the new one I was no able to find the vacuum tank (number 1 on diagram), someone of you know where it is located?

Thanks in advance..
