Clamps on air intake

[GTP in RTP]

Now that I look at it...it might be to a previous-gen car that had a 4T60-E vac. transmission...so don't worry about that line...you have the 4T65E-HD...no vacuum lines needed

Thanks, that what I thought.
I just need to replace the hose, previous owner had it rigged up badly. Is there a reducer on the tb that takes the size down to match the purge valve ?
I assume that would be the correct way, prev owner has big hose with an adapter connected to the smaller hose.
