2001 R1150GS - The Fuel level indicator was acting up last fall and yesterday the fuel level dropped to nothing with only 148 miles on the tank. No low level light came on yet so it would seem that the light and the fuel level are 2 different sensors. I have never replaced the fuel filter or had the tank open for anything other than to put gas in it. At times last year when I knew my fuel was low the LCD screen would indicate full and then drop down. As I mentioned, erratic behavior appears to be the norm now.

Since I should probably go in and replace the fuel filter is there something else in the tank that I should be looking for or parts that I should order before I even start?
