Fuel Cap
Fuel System
Seals the fuel tank and maintains proper system pressure.
The fuel cap seals the filler neck to prevent fuel vapor from escaping and keeps the fuel system's evaporative emissions loop sealed. A worn seal lets vapor escape and can trigger an emissions fault.
⚠️ Owners Often Notice
If the Fuel Cap is starting to fail, these are the signs owners most commonly report before it gets worse:
