It is a gas under pressure and doesn't really move around because of turning forces. You might be close to the culprit though.. Sometimes the condensate drain for the a/c system clogs up and the plenum starts to fill with water. I had an old Cadi that would dump about a gallon of ice water on your feet during a turn when it clogged. After a couple of times of this happening I learned to keep that drain clear! I don't know exactly where the drain is on your hose but it should be coming out the passenger side firewall area. Steve B.
