Q: low fuel level warning light is on all the time. on 2004 Hyundai Sonata

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Low fuel level warning light is on all the time since I had the fuel regulator replaced. I cannot ever seeing that light on when the tank was full. Dealer says its ok, I do not believe them. Book says that it could damage the catalylic converter if it is on all the time. Want to protect my guarantee, 10yr, 100,000 miles. Please help.
The low fuel light could be due to something going wrong when the regulator was replaced. If the check engine light is flashing, it's trying to tell you that there's an engine control problem and catalytic converter damage is imminent. But not the low fuel light. Don't worry about the low fuel light signifying a danger to the catalyst. Could be that the person at the dealer wasn't hearing you correctly.
