The Best Gas Caps to Keep Your Fuel System Sealed

The gas cap is one part of your vehicle that we bet you don’t give much thought to in spite of how often you use it. The thing is, a gas cap does a lot more than simply close off your vehicle’s filler neck when you’re done gassing up. Your vehicle’s gas cap is part of a complex emissions control system that helps prevent pollution that can cause environmental harm. Specifically, the gas cap seals your car or truck’s gas tank against escaping gasoline vapors.
