Do you have venting issues when emptying your Rotopax? I can't see a separate vent path in this spout, which would make it slow and irritating to use. They talk about a 2nd vent cap, but my
4 gallon containers only have one opening, so it's necessary to both dump and vent from one opening. For a buck more you can get a
Rotopax water spout and it works fine. Still a little slow but so much better than the supplied CARB fuel spout and the sides of the container don't get sucked in from the no vent issue.
I like the beefy construction of the Rotopax compared to other plastic fuel containers and mine don't leak at the cap which is critical because I carry mine horizontal. They're more expensive than most, but if you've handled them, you can see the superior construction.
