Fuel tank vent fitting ?

Thomas Kleman

On SM2K 422 there is a outlet fitting and hose at the top aft of the fuel tank. It runs down the scupper to a "T" next to the genset muffler. One leg runs back under the Yanmar and I can't see where it goes. Is this an overfill/expansion feature and if so where does it terminate ? I assume I get fuel in my bilge if this ever happens......and where does the other leg go (sort of disappears under genset).
