I agree with you Mr. 67Dart273, the problem he experienced must be with his specific fuel gauge. This fix should not be appropriate for everyone.
Also, they make variable VRs that can be tweaked to get any range of voltage readings out of them for extra fine tuning, should this help anyone. For example, you may want 5.7 volts to get to the full reading, so after filling the tank, just adjust the variable VR until it reads "full".
I like the way you worked to figure out a solution for your problem. However I would have suggested replacing the gauge with one that had fewer hours it before going thru all the trouble you did. Though maybe your pride (deserved) and satisfaction was worth your efforts. Kudos to you sir!
