For those of you that are using the euro style jerry cans for fuel storage and don't like the cheap leaky pour spouts that are available from most of the places that are selling the fuel cans. Here is a place that carries the correct swiss spout for the cans. A little on the pricey side, but well worth it for a spout that works.
http://www.swissarmyvehicles.com/showdetails.php?cat=surplus&partno=SAV4220I have no financial affiliation with this company. Ordered on-line and a few days later two new looking pour spouts show up. The only problem i can see with these is the end (it does have a removable filter/strainer) is to big to fit in the filler hole of a vehicle that has the restriction plate for unleaded gasoline.
