Charcoal canister hookup with non EGR carb

[runner74]

This has probably been posted before. But I need a refresher about the canister with new carbs.

1974 bb400. Carb is Street Demon

Canister has bowl vent line but new carb does not. What to do with this line? Plug at canister?
Canister has Purge line. Can I just hook this up to PVC/Vacuum line? as original?
Canister vent line still intact. No change.*

*Or just eliminate and get a different vented Gas cap?

Any diagrams or pics welcome

Thanks
