Changing a fuel cap is a simple but important task that can help keep your vehicle running smoothly. A fuel cap prevents fuel from evaporating from your gas tank, and it also helps to keep dirt and debris out of your fuel system. Over time, fuel caps can become damaged or lost, so it’s important to know how to change one if necessary.
Most fuel caps are located on the rear quarter panel of your vehicle, behind the fuel door. To change a fuel cap, simply unscrew the old cap and screw on the new one. Be sure to tighten the new cap securely to prevent fuel from leaking.
