Fuel tank connection under trailer hitch?

This is my 83 C20 Suburban. It had this air quick connect mounted under the reciever hitch with a rubber hose hat runs to a connection in the fuel filler tube.
What in the world is this for? I can't imagine it can suck fuel out of the tank because of high the fitting is. Is the fitting on the filler tube supposed to be there? Is it just supposed to be a vent?

Thanks in advance...
Blake
