What does this hose go to? Attached to clean air of the air filter assembly.

 

Not 100% sure but that might be part of your TAC (thermostatic air cleaner) system. You'll have multiple hoses, check valves, and vacuum motors that mix hot and cold air in the air cleaner for various fuel/air mixtures.

 

I can't find where this hose goes. There is no missing hose connectors unless a part has been removed. Can somebody please send a picture of theirs. Thanks
