Since i bought my early 2000 tahoe the fuel gauge will twitch , also notice whining noise through stereo while its doing it, not and all the time thing . But enough to be a pain. Done a little research and i am told it is a chronic problem on the early tahoes, but unable to find any bulletins on the subject. Was told the harness that plugs into the fuel tank rubs on the frame and causes the problem. Any body heard of this ? Or can point me in the right direction ? Thanks mike b.
