Vacuum question

Vacuum question
In the attached image, the red line coming from the front of the UIM doesn't have vacuum. Is this boost only? I have an HKS racing BOV that has a port for vacuum and a separate port for boost. I already verified there is no vacuum from this line, so I am curious if anyone knows if it is a boost line. I am also curious about the red line coming out the back of the UIM because it doesn't have vacuum either.

Neither is vacuum. See the attached jpg of the purge valve and how the line going to its top goes to the throttle body to a source that is Prior to the butterflys.
On the back the only one that is vacuum is the bottom one.
