went out to take a look at the vacuum hose attached to it (where winfred suggested to do the water induction). very lightly checked the slack, and thought to myself, "this is a hell of a long hose"...until i get to the end of it. anyone know where it goes? etk doe4sn't show. i would estimate that its been disconnected for 18k miles, might explain my city gas mileage and my ping. thanks.
