My fuel gauge on my 97 Tahoe has been dancing for a while. I just used the trip gauge until the fuel pump actually started going. So I figured I'd replace the pump and sending unit with the hopes that would fix the gauge. It didn't...and the gauge has steadily gotten worse until now it will spin all the way down and catch on the oil pressure gauge needle sometimes. I've also seen where people repair the stepper motor, but the bang for the buck isn't really there. So...I figured I can find a new instrument cluster relatively cheap and swap it. If I do this, nothing will match my 270K, which I would like to retain. Is there a way to run up the mileage on the new cluster to match the one I plan on taking out? And, for that matter, is there anything special I need to do when swapping these, other than just plugging all the harness wires and such back in?
