Vacuum lines

[Newsguy]

Thanks for the info. That isn't covered in the manual, or I missed it.
I intended using the original, but I need to know how to connect the vacuum lines since I am unable to copy the setup from the other engine. The new one was a long block.

This thread has some pretty good info. You need vacuum for the SAI system and flapper valve.
Where does this go - vacuum valve

If it's a Tiptronic, there's also a vacuum connection to a valve for transmission cooling.

Thanks, I'll take a look. It is a manual.
