I have an '07, 2220 and the fuel gauge, which is digital, has never worked right. Today I know I am down to about 10 gals of fuel and its telling me that there 99% left. To go even further the gauge is also saying there is 40 gals left in the 60 gal tank. So no matter which you look at fuel used, fuel left, total fuel,, none are right and this is the third gauge the dealer here in texas has put in. I could really stand some help here!!
