vacuum pipes

I have installed a 1641 engine with a 32/36 weber carb in a '72
bay. Question: The vacuum return pipes from carb to fuel tank: is it
necessary to keep them or can they now be discarded and blocked off? :)

The tank needs to breath, and feeding the fumes into the airfilter is the best way to do that.
