JDMv300

Hello guys, I would like to get help with an issue I am having with my '03 Lexus gs300. My gas gauge is acting very weird, from one day to another started doing this issue that everytime I fill up my car it would take 10-15 minutes for the gas gauge to go up to full. But it got even worst, last week My car had half of tank of gas and the gas gauge went all the way up and then began to go down and it went back up again. Can somebody tell me what can be wrong? I dont really know that much about cars, and i also tried my best to explain it the best I could because english is my second lenguage. Thanks

JDMv300, it sounds as if there may be a concern with the fuel sending unit but without a diagnosis we cannot be sure. We recommend you have your vehicle inspected by a Lexus Dealer as they would be in the best position to determine the cause and suggest a remedy. We apologize for your inconvenience
