My light has been on for 5 years. my mechanic states it will cost $300 plus to fix and I have not had the repair. initially it was thought to be a leak in the gas line or fuel tank however the line has been checked and the gas tank was replaced as it rusted through. FYI I have NEVER had to replace a gas tank in my life and I have owned some old junkers in my time.
