Thanks Dave for taking the time to post the picture! Mine is different in the fact it has clamps to hold dual , two hoses not just one ? I will post a photo later today. I connected hoses yesterday like your but the valve remained closed after running the engine for a while, it was in the mid eighties outside temp, figured it should have opened up at that temp. If I connect a line directly to carb port it closes up, disconnect the hose and it opens up so I know the valve works on snorkel
