Every month or two, I take the connector apart and soak in in PBW for awhile to clean it. Dip all the parts in Star San and reassemble. The gas line will be clean enough that you don't need to put any sanitizer in it. If beer has backed up into the line, it needs a lot more than just sanitizing. Complete cleaning with BLC or outright replacing is in order.
On a side note, anyone ever take apart a cobra/picnic tap after a long time of use? Holy mackerel, they get super gunked up with crud up inside the plastic housing. Definitely worth a cleaning from time to time if you use them.
