I suspected as much since the nut on it is SAE instead of metric. Does yours have a hose barb (nipple)on the tank? mine is a threaded male connection, the steel line has a brass compression fitting on it.
on mine the steel fuel line runs from the tank, under the heat shield plate to the upper edge of the right side "firewall", then runs to the right rear to the electric fuel pump, then back to the front of the ZF, crosses over the ZF support behind the alternator turns toward the engine between the alternator & A/C compressor to the carb feed.
I've never worked on another goose, so this is my sole reference.
