Fuel filler neck install

Before you get this all nailed together make sure you have the right setup FOR A TANK VENT or have one at all. Now is the time to deal with it, and if there is ANY thought at all about vapor return for a carb, or pump regulator return, or maybe later on EFI now is the time to get the tank/ vent/ return set up
Right now I am going to have it as a dead head really don't know how to add anything the tank has a nipple for a vapor line that had a steel line that ran to the charcoal canister and I believe up to the carb but this is a new tank with a aeromotive electric fuel pump externally
