One end of the vent line--which is most likely to be a 5/8" ID hose--is connected to a fitting on the top of the tank. Start there and trace the line, which can be anywhere from 3-25' long, to the thru-hull...which most likely is the same type of thru-hull as those on the fuel and water tank vents.

I see you've just joined our merry little band...welcome aboard!
