Vacuum leak
My 99 Expedition through a vacuum leak code. The leak was easy enough to find, but I can't find where it attaches. Anyone have a idea?
Thanks

Don't know for sure, but I do see something suspicious at the red arrow as well as what looks like a broken-off vacuum port in that loose connector.

Alright then, it was something that looked odd..

Unfortunately, you've zoomed in too tight to see what else is in the area.

I think that line attaches under the vapor purge valve on the firewall. I remember removing the vacuum tree when I replaced my intake.

Check under the purge valve for the small vacuum port.

It broke off that vacuum valve right behind it.

Well, no wonder I could not find it. The nipple broke off the valve. I guess I'll need to replace the valve.
