CDR Valve hose

[Hummer Guy]

I have a hose that's coming out on the driver side by the windshield washer fluid reservoir that puts out a little smoke while running, this is one of the small hoses from the CDR valve, where is that hose suppose to be at?

I believe it is part of the deep water fording kit vent hose... I think there is one that goes to the valve they remove and one that goes to the sensor cup that had also been removed. (demilled)
