This accessory made the functionality of my Tuff Jug(s) WAY better when filling up my Ford that has the capless fuel fill setup.

With the spout adapter on the vent tube doesn't work, so its very slow to add fuel to a car gas tank. All the air comes in big, slow glugs. Takes forever.

It doesn't screw onto either of the 2.5 gallon jugs that I bought. It has no threading in the adapter, no sealing o-ring, and nothing that I can figure out even how to get it to screw onto the jug. To me it is useless, or maybe not even made for the 2.5 gallon jug.
