Judging by the direction of the arrow on the fitting I figure whatever it is feeds into the exhaust.
Two lines fuel systems have one line from the fuel tank to the carburetor and a second line from the exhaust going to the fuel tank to provide tank pressue to push the fuel to the carburetor via the other line.
