The one from your intake manifold should go to the vacuum petcock. The vacuum from the intake causes the petcock to open, allowing fuel to flow to the carb. To check if you have it connected properly, disconnect the fuel hose from the carb and crank the engine. If fuel comes out of the fuel line while the engine is cranking, you're good to go, and I would move on to checking the valves. Or it's also possible you didn't clean the carb well enough.
