No frustrations with these after I changed the vent types on the 5 gallon cans. This doesn't show the ones for diesel. It takes a lot of plastic containers to maintain the Ponderosa.
I have two nospill cans. Both work great. They used to be hard to find. I got mine many years ago in Kansas City at Air Parts. I think the guy that invented it lived in the area. It took a while but I see them all over now.
