My main issue with this part is that it is to be used ONLY with Moeller Scepter cans. Nowhere in the description does it ever mention that these are only to be used for Scepter tanks. I tried to use these as a replacement on my current cans and more fuel leaked from where the spout screws to the can than out of the spout. I cant comment on the poor construction or the fact that they dont last for very long, as I gace them less than ten minutes of my time before I packed them back up and came to the computer to print out a return label. Amazon should clearly state that these are to be used with the same manufacturer gas can to avoid any further confusion.I agree with so many others that the new eco freindly spouts are pure garbage. I have yet to find one that last and that does not spill gasoline. None are easy to pour into lawnmower/snowblower/weedwacker fuel tanks. The restrictions have turned refueling your equiptment into a two person job.
