John, that's somewhat like I thought. Just so used to the modern parts
that actually have constant voltage. Oh for an oscilloscope!

Yes it would be so easy to stick 3 terminal voltage regulator on it. One
that I could fine tune with a pot on the fuel gauge to show a full tank. 

Without a known good way to check the voltage stabiliser I may try a
regulator and see how well it works. Maybe I have one in the old parts
bin or I could build one with some power transistors I know are in there
if I had a schematic.
