If you have ever gone through the tedious and laborious activity of dispensing fuel from your gas can, then you must have encountered that rigorous splash as the liquid sprouts out of the can. That is about to change. In the U.S., gas cans and containers came with two vents, previously. Now, they only come with one opening for pouring and filling. There's a need for a sufficient pressure difference for a steady and continuous flow of fuel out of your can. A gas can vent provides that pressure difference. And just like every dog needs a home, every vent also needs a cap. After some thorough investigation, the options below are guilty of being the best gas can vent caps in 2021. We have also done our research to provide you with all the information you need to buy one.
When you pour out of a regular can, you experience some resistance which only happens because as you pour out of the spout, there is a pressure build-up due to the trapped air in the can. If you pour too quickly, you will end up splashing fuel all around and making a big mess. The better option is creating vents by simply puncturing a second hole at the other upper end of your gas can. So now that you have a hole, how do you seal it?
Gas can vent caps provide a means to dispense fuel, water, and other liquids quickly and smoothly. They sure save you time and effort. We know there are way more options for vent caps as there are B films on Netflix. So we thought that you might want to know what you're buying and how it works to make the right purchase.
How does a vent gas cap work?
What gives a vent gas cap its mysterious abilities is air pressure. When you pour out of a gas can through the spout, the air around you is constantly trying to get in through that opening. And like a truck trying to take a one-way, there is some fluid traffic. This traffic is reflected in the inconsistent flow you notice as the liquid is pouring out. Pressure continues to build inside the can as the air continuously gets trapped. If you pour too quickly, the gasoline will splash out uncontrollably.
A vent creates an equal and opposite pressure that balances out the air pressure pushing in from the spout. This allows a steady flow of gasoline even when you pour out quickly.
How do you install a gas can vent cap?
Installing a vent gas cap is kid’s stuff. First, you want to drill a 1/2" hole into the high back of your can, using a step drill bit preferably. We recommend drilling into the high back because the only other option is the handle, and handles are usually quite thick. After drilling the hole, you push the vent cap into it and make sure it sits tight to avoid any leakages. Voila! You have yourself a vented gas can that will pour effortlessly every after.
How do you replace your current vent cap?
Just like every other thing in life, a gas can vent cap doesn't live forever. If you notice that your vent cap is deteriorating or damaged, you can replace it easily by installing a new vent. To do this, you first want to empty the gas container and dry it out inside and outside. Then using a screwdriver, you carefully but assuredly pry out the old vent cap and dispose of it as you would any other piece of plastic that has paid the price of service. Finally, push the new vent cap tight, and be sure it fits and doesn't leak. Some vent caps may require a sealer. Do not use silicone rubber. Seal all is typically the better choice.

Gas Can Vent Cap FAQ
Q: Why do I need a vent on my gas can?
A: A vent is an opening that allows gases or liquids to flow into or out of a container. Gas cans used to have two vents before, one for pouring and the other to help maintain a steady flow of gasoline. Nowadays, gas containers have only one spout responsible for pouring and venting at the same time. So, essentially, you have been tasked with creating a vent yourself if you want a steady, controlled flow of liquid in and out of your gas can.
Q: What do I need to install a gas can vent cap?
A: To install a gas can vent cap and say goodbye to slow pouring, you need a drill, wrench, and of course, gas can vent caps. Luckily, some sellers include all of these and more in the kits that come with your purchase. So choose wisely.
Q: Can I use gas can vent caps for containers with other liquids?
A: Gas can vent caps have a wide application. They can be used for plastic or metal cans. They can also be used with other fuels and liquids like diesel, kerosene, paint, water and any application where you need a smoother, faster flow.
