I don't understand those connections, Paul. If that is an air purge system, rather than an old-fashioned primer, there has to be a fuel return hose going to the fuel tank. How many hoses come out of your fuel tank? Where do they go?
If those connections you listed are correct, then for sorting out the primer problem, you do not need to connect the blue circle or red circle hoses: they are just open at the far end anyway when the engine is not running. That means you only have two hoses to find homes for. Suppose for a moment that you have those two correct: green circle to primer and yellow circle to the fuel suction line. When you push the primer and release it, fuel would be sucked up through the hose that terminates in the submerged filter in the tank, if those two hoses are correctly identified and there is nothing wrong inside the carburetor or primer.
