Went on my first longer ride after buying my 04’ today. The tank was Almost full when I left and after 62 miles the last dot on the fuel gauge was blinking. I pulled in to put gas in and it took less than 3 gallons. It went to full on the gauge. After I got home and put it in the garage I thought I’d check what the gas gauge said and there was only 2 dots? I turned it off and back on and it said there was only 1 dot? Did it again and there was 4 dots? There’s no leaks that I’ve ever seen or noticed. Any idea what the issue is?
