Has someone tried syphoning my gas?

Hello, there is no reason to expect that someone tried to syphon your gas from these concerns alone. Physical damage is possible and verifiable if you trace down to the possible cause of evaporative emissions system leakage. Testing will be needed to find out what code is present. Then, it will be necessary to trace down to the root cause of that code. Some experience will be needed as well as some proper equipment to test the systems.
