Got the feed and return hooked up correctly I think. Been reading the damn service manual and got fed up so I figured I'd ask.
Going straight carb with no canister only the tank vent valve

The larger or the two bare should go to the tank valve mounted above the rear axle. The smaller of the two should run to the vapor purge canister at the front of the car
