About

Fuel Cap

Stay Safe and Secure Thanks to the Right Fuel Cap
Your vehicle's fuel cap does a lot more than simply seal up the space between your gas tank and the outside world. Even standard caps provide a crucial layer of protection that not only prevents your car or truck from losing gas while you're on the move, but also prevents harmful vapors from escaping your vehicle and dirtying the air around you. We offer the lowest prices on fuel caps of all shapes and sizes at AutoZone so you can restore the functionality of this part of your gas system and get back on the move again without breaking the bank.

Don't Put It Off
The main reason you may need to consider changing your standard fuel cap sooner rather than later is an upcoming emissions test. Many state governments opt to test gas caps for efficiency during this annual test, and a cracked, chipped, damaged or missing gas cap will cause you to fail the examination. This is because your fuel cap helps to normalize the pressure within the tank itself and keep harmful vapors inside while ensuring gasoline stays inside of your car where it belongs rather than polluting the roads you travel. Rather than running the risk of failing the test and having to pay for it twice (as long as potential delayed renewed registration fines), it's easier and cheaper to simply search “fuel caps near me” and head into your local AutoZone shop to find a replacement for your existing cap.

AutoZone Knows What You Need
Installation of a new cap is as simple as removing the old cap and then twisting the new one into place. The real test is finding the right match for your tank and one that covers all the bases in terms of regulations and legal requirements, details which staff members at your local AutoZone store can help you out with. There are a few other options you might want to consider as well, including locking fuel caps. These caps can be used to prevent unwelcome parties from accessing your tank for any reason thanks to the addition of a lock that keeps the cap from twisting off without the use of the included key. This adds an extra measure of security to your ride and helps to keep your expensive fuel in your tank where it belongs.

Simple Shopping Trip
Whether you're sticking with a standard cap or upgrading to a locking model, we're here at AutoZone to ensure you always have easy access to the best fuel caps for cars and trucks no matter what your needs happen to be. Keep your engine safe and healthy, reduce pollution and ensure you're never wasting expensive fuel by getting a new cap that can handle the challenges of the road ahead. If you're concerned about choosing the right cap to meet regulations, don't hesitate to visit your local AutoZone location and ask staff members for advice on your purchase.
