Fresh Water Tank Overflow

Looking for the fresh water tank overflow hose. At this time when the tank is full the water runs out of the basement. I have found a hose that comes thru the basement near the black/ gray dump pipe. There is split panel (picture attached)
I was able to remove but the hose I thought could be the overflow goes up thru the coach floor.

Usually the Overflow hose is about a 2" diameter corrugated white and blue hose, suspect it may be leaking where it's slips over the tank vent/outlet.

Look in the bay and above the panel in front of the passenger side duals. If OEM it will discharge thru the bulkhead in front of the curbside duals.

You are looking on the wrong end of the wet bay.

Expanding on Justin's answer, here is a photo of our curb side bay in front of rear wheels.  You'll probably need to remove a cover panel to see this view.  It is held in place by multiple screws and some caulking.

If your coach is laid out like ours, it will be very difficult to reach (or even see) the top of the fresh water tank where the overflow hose is connected.  Our water heater is in the way.  Will take some long skinny arms with very dexterous fingers to reach the hose clamp.  Good luck!

Yes.  They run across the top of the fresh water tank to the street side wet bay.  Connections are up above my hose reel.  They are not factory - were added at some later date by a previous owner.
