Like Oliver and Jack said it was a sight guage for the waste tank. Mine still has it. In addition to being a sight guage mine also has a hose fitting plumbed into it for flushing the tank. I use it fairly often.
The tubing on mine has yellowed to the point that I can't see how full the tank is, bot I do like the wash out port.
My waste tank has ports in the top, left, and lower left front side when you open the inner water bay door.
