Just an FYI: we have had issues with the one sided self stick gaskets that a lot of parts stores are selling. They start leaking after install. Another source is to make sure the hose surface on the housing and ID are both clean. I have had more than one hose leak make me think it was the gasket. Lastly a good idea to retighten the clamps (worm gear) every so often until they take a "set" .
