You could probably stick the outlet hose over the spigot on this carrier, open the spigot valve and let gravity do it's thing. Check out the Dromedary line of water bags, they sell adapters to fit between water filter and wide-mouth type Naglene bottles/water bags that will adapt to the Camp Filters outlet hose.
 This is a nice item, easy to pour water out of, and folds small.
