All of our Wavian Jerry Can systems come with an EPA, C.A.R.B. and DOT
approved spout. We have also added an adapter since some gasoline
powered vehicles need a smaller spout to fit in the filler.The adapter
sits on the spout and needs to be turned clockwise until it snaps into
place .The spout needs to be pushed to start the flow. The weight of the
gasoline helps to open the spout to facilitate an easy quick pour. All
Wavian products have a 2 year warranty against manufacturers defects.
