Review on Upgraded Fuel Gas Can Vent Caps With Lanyard Attachment - Improve Gas Can And Tank Flow - Kit Of 12 For Quick Dispensing From Water Jugs And Fuel Tanks by Eric Teshome

I HATE the "new" style gas spouts. They're bad enough that the "aftermarket" has responded with "old" style spouts and breathers.These are a nice addition to an old style spout, to add a vent cap to a fuel can. They are easy enough to install, and so far have not leaked. My only complaint is that the rubber internal square ring ripped, but I was able to fix that with a new o-ring. Also, if the cap had a tether, they would be perfect.
