81 911 SC Vacuum line help

[dugr]

I've got an 81 911 SC that I'm trying to trace a vacuum line from the "T" where one side goes to the decel valve and the other is a mystery. The WUR on this one just goes to atmosphere at the top of the intake butterfly with no vacuum nipple.

I've read the posts in 81 SC Air Box & Vacuum Leaks but, that question didn't get answered or, was something I missed.

Below are the images from the other post that I'm referring to.




I've added arrows that point to the line in question.



Thanks,
Doug

Other end goes to the cruise control.

Thanks for the input. I didn't mention it but this is a 3.5mm hose, the cruize is larger.

Thanks! I didn't notice it was behind the other hose.

Again, thanks for all your help!

Yep, 2 hoses. Larger line is vent and the 3.5 is vacuum
