Frequently Asked Questions (FAQs)
1. Should gas caps be vented?
Your tank has to breathe. In order to breathe, your tank must have a vent somewhere that will relieve both vacuum and pressure. Gasoline expands in volume as it warms up and shrinks in volume as it cools down. The fuel level of your tank changes throughout the day, even if you are not driving it.
2. What is the difference between a vented and non vented gas cap?
Vented caps are used mostly for emissions control. You could use either one, but for the sake of keeping fuel pressure more consistent, I'd go with the vented cap. Vented caps were pre-emissions. When vapor canisters were added to cars, non-vented caps came into use.
3. Are ATV gas caps universal?
The sizing for ATV gas caps is generally the same- hence the ability to create a universal gas cap that can fit all brands. However, some ATVs have alternative gas tank options and even use a differently shaped cap.
4. Do motorcycle gas caps vent?
Premium Member. The gas cap should NOT be vented. The tank has a separate vent line that runs to the evap canister to collect fumes instead of releasing them to the atmosphere. Some people remove the evap canister, but you still leave the vent line open to the air.
