Review on 🔥 Fuel Gas Can Vent Caps - 6 Pack Metal Replacement Fuel Tank Vent Plug - Leak-Proof Gas Jug Vent Caps for Faster Flow and Efficient Gas Tank Exhaust by Daniel Espinoza

I had a poorly ventilated gas cylinder. So I had to keep tipping the 5 gallon can up and down to break the vacuum. This jar was only a few years old and I can't find a 5 gallon jar that fills well with a vent. Now I made my own with these air vents. Really easy to install. I emptied the plastic jar and filled it with water just to be on the safe side before piercing the whole thing. BUY THIS PRODUCT!
