I own a '95 Z/28 convertible that I purchased 3.5 yrs ago. Ever since I have owned it, when I would fill the tank full of gas, the needle on the gage would go about a quarter of a tank past the "F". In direct relation, when the needle got between half a tank and quarter of a tank, you had better start heading for the gas station (found that out the hard way). Anyway, I recall watching HorsepowerTV a few years back that talked about putting in aftermarket "faces" behind your gages. They stated on the program that what you would want to do is start your car, make note of where the needles were and then shut the car off. Then take your dash apart, pop the needles off and change the faces with the aftermarket piece. So I got to thinking to myself, "this is what I need to do to my fuel gage". I just spent the last 2 hours in the driveway, sweating profusly, trying to accomplish this. Once I got done and bolted everthing back together and started the car, I was looking good. That is until I shut the car off. As soon as I did that, the fuel gage went to about 3/4 of a tank past the "F". When I started the car back up, it moved back over to where it should have been.

My point to all of this is, did I perform this procedure correctly? Is there something that I am missing? Just want to make sure that my baby stays factory pristine!!
