Hi all, I've been chasing an issue that has been plaguing me for 2 month now. Yesterday I finally to do a boost leak test and pressurize the system to see if I have a boost/vacuum leak. Well I found out the source of my leak and it was a vacuum line connected on the passenger side horn (in the center of the horn on the inside). I cant trace where this line connects to so I'm posting here to see if you guys have some input on where this line may lead.

My questions are:
1: where does this vacuum line lead because i suspect it may possibly be clogged?

2: does your car have a clamp around this vacuum line where it slips over the nipple.

See pics of where the nipple is located (roughly)

 

Nevermind, figured it out thanks anyway

 

Glad you found it! Be sure to update the thread with the solution you found just in case someone stumbles upon it and has the same question as you.

 

Thats true, it was a vacuum leak from the nipple on the passenger side horn (on the inside). The hose popped off the nipple (same hose that is connected to the fuel pressure regulator)
