4X4 Vacuum Issues

I have 2008 6.4 Powerstroke, had to do the thermostats and had to have the driver side battery tray/ Degauss/ Vacuum reservoir out. There are 2 take-off the vacuum reservoir (under the battery tray), small one goes to a tree, one way from the tree goes to the vacuum pump the other way it goes the 4x4 solenoid. The other hose I am missing (4c3z-9c493-AA ford part number). What I can't find out is where the other end of the that vacuum hose connects too? Ford schem doesn't show it. My mechanic thought it was a drain for the battery tray, my ford parts guy thought it went to the degauss, it appears like neither guess is right. I attached the ford schem the call-out part number is "9C493". It shows the 1 end connected the vacuum reservoir the other end goes nowhere.

I've been locking the hubs manually for a little while now, would like to fix it while I have it apart. Thanks for the help

EGR has never been deleted. EGR was replaced once when it was still under extended warranty in 2009 or 2010.

What is it that you're calling a "Degauss"? Haven't seen that term used since I had to degauss CRTs 40 years ago to demagnetize them.

Degauss is the coolant bottle.

The correct term is "Degas", not "degauss".

I have seen the spelling both ways, kind of like colour and color.

I don't speak French, but perhaps that might be a French translation. You'll never see "degauss" used for a replacement for "degas" by any English-speaker who knows the subject matter.
