I had an older 83 GMC Jimmy K5, and it had some gauge problems too. After removing the gauge panel and all, I noticed the gauges made their connections via some metal clips that attch to pins ont he back of the gauges. Well I had a fuel gauge that was inaccurate. it would not show a full tank when there was one. I found out when taking apart the cluster, that the fuel gauge was not seated correctly in its pin sockets.

After i made that little adjustment, the gauge worked perfectly.

Perhaps it is just a loose gauge..
