i've no direct experience but goog indicates that it seems like it is a common issue, that hose & o-rings dry out and/or loosen over time.
swap the hose for a new one. you might want to buy two new ones just in case - seems like the issue can recur. Also make sure air filter didn't get soaked with fluid and swap it if so.
