How fast you guys forget about the years you spent around cars with carb's. Remember the black strip on the roads especially on the lane going up a grade. This was from the crankcase puke tube that were later replaced with PCV (positive crankcase vents) routed back into the carb. Then big bulky closed air cleaners with all those vacuum hoses to a charcoal canister. Gas tanks with non vented caps and so on.

Our Hot Rods have open element air filters sitting on top of the carb with fuel vapors venting into that open filter. The carb is sitting on an aluminum manifold heating the fuel making more vaporization when parked. You can run hoses to each bowl vent and hose from the fuel tank all routed to a charcoal emissions canister. Then a hose back into the engine intake for vac. source but would still have some vapors if engine was not running or providing vacuum. You worked so hard to create a mean, nasty, smelly hot rod. Congrats you have succeeded !!!
