Just to clarify, shouldn't there be THREE pipes connected to the underneath of the tank?

One provides fuel to the fuel pump and on to the carbs - this one is connected to the tap underneath the tank.

There are then two small breather hoses. One is as you described to allow air into the tank to prevent a vacuum and the other is for fuel over-fill and water drainage.

Pretty sure thats correct, but feel free to correct me if im wrong.
