This has been covered somewhere on this board before.

The original line from the T to the tank has a one-way check valve in it.  It is actually hidden in the line itself, so often it is thrown away when someone replaces that line.  Check valves were common on that era car and can be found and adapted if you lost yours.

Anti-syphon is needed only when a vehicle's tank fuel level is above the carbs and the head is enough to force the carb needle valve off of its seat.  While not common, it has happened.
