3rd Fuel Outlet/Inlet??

Have a 1978 Chevy 3/4 ton 4x4 with dual side fuel tanks. 3 outlet/intlets come out the top of the fuel tanks. Two of these outlet/intlets are obviously fuel source and return but what is the third for and where is it supposed to go?

Look for about a half inch diameter rubber hose going to the charcoal canister in the front of the engine compartment. That's to collect vapors as the fuel warms up and expands.
