I use a 3/8" ID fuel hose connected to the front carb air filter.

A PCV valve would replace the road draft tube and connect to the intake manifold (vacuum wiper connection).

I used to have a PCV valve with a condensor filter, but went back to road draft tube, as it works better at sustained high rpm.
