[VAC] Re: Seen advise

On the front mounted water tanks pre "Control Center", there is usually 
a clear vinyl tube (sight glass) in the forward curbside corner to the 
side of the sofa or under the dinette seat.  It runs between the 
overflow fitting on the top and a drain fitting on the bottom of tank.

I've seen all sorts of owner added level marks, from Felt Tip marker to 
Dymo-Labels to computer made decals.

If for some reason yours is missing, it's a good weekend project, as 
all parts are hardware store items.
