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 Ron Collins

A bit difficult to install, specifically keeping the inside piece from twisting while tightening the outside. Drilling was easy and using the included wire to get the valve seated in the hole was pretty straightforward. I only got it rightfully hand tight but it’s been liquidproof and vaporproof now for many months. It’s easy to use and makes the flow rate fantastic.
