I took my 04 in and had the work done, haven't seen any noticeable improvement. Last week I was driving to Kansas City and after about 390 miles on the tank of gas, the last bar started flashing and it beeped. I stopped and put in 3 gallons of gas, enough to get me to KC but when I started out again the last bar was still blinking. I stopped, shut down completely and started again, still blinking. I reset trip meter B so I'd know how far I'd driven and went on. When I filled up in Kansas City, about 70 miles later, It only take about 7.5 gallons. The fuel gauge is not completely worthless but it's close. The trip meter is what I go by.
