NOTE: The top grip area of the cap received may appear different than the cap pictured. This will not affect fit or function of the cap. It will work the same as the factory part.Your fuel system uses both vacuum and pressure to ensure that as few gasoline vapors reach the air as possible. The gas cap regulates this balance. The cap has relief and pressure valves that regulate the pressure in the tank. Over time the gas cap can cease to work properly due to dirt, wear, and damage. In modern cars this will cause your check engine light to come on (usually after you fill up). If you notice your check engine light comes on after a fill up first check the cap for tightness. Then give the light a few days to go off. If your gas cap is the culprit then this replacement is what you need. Most cars the light will go out after 10-12 cycles of the key as long as nothing else is affecting the fuel vapor system.
