Yes GearNut, the tank has two hoses and I figured out which is which. The question is the carb, it has two small dia tubes and a larger one. I assume the the larger dia is the overflow. The other two, are similar in dia and one is on the left and one on the right. The left side is horizontal to intake while the left is vertical as the larger one. Theres also some sort of manifold on the back side of the engine, with same dia tubes with two arrows pointing in opposite directions.
