Edelbrock Fireball!!!

Problem, I have the regulator and no gauge (getting one this weekend) not sure about a fuel return vent. It seems like it wants to fire up just wont quite get there. I dont want to flood it by pumping gas, but it seems like this is what its asking for. However I stuck my fingers down in the carb... (without a buddy turing it lol) and its wet so I know fuel is getting there
