I've got a 2004 GMC sierra and the gas guage just went to zero with the light on.  I saw a year of so ago there where some posts on this subject but not much info.  Has anyone fixed this problem and where did they start? I do a lot of agriculture field work so keeping track of mileage is not as effective as road work.  Hopefully there is an easy fix or some fix.  Thanks for your time.
