I have a 97 s-10. The problem I am having is that the fuel guage is fluctuating radically. When I fill up the guage shows full, no problem. As I get about 50 miles out of the tank the guage begins to drop rapidly and by the time I have about a half tank left the guage is showing empty. Some days the guage works fine but most of the time it fluctuates badly. I've been trying to watch to see if dampness plays a factor but to this point it hasn't. I have not been able to pinpoint any set pattern. The rest of the guages have been working just fine with no fluctuations.
