Least Shoddy Fuel Sending Unit?

Oh? In the electronics world, that would be considered out of tolerance and would be pitched in the garbage. You might consider replacing it.
My 7806 regulators would start at exactly 6 volts and would heat up and be at 6 volts. I bench tested it under load for about a week before installing in my car. Then I made a spare just in case.

OK to be more exact... Starts ranged from 4.88 to 5.02. after 10 minutes 5.02 to 5.42. All with no load on output, just run to test before packaging. The prototypes ran in my 67 and our 73 for 18 months before the 1st retail unit went to market. I shipped over 360 units during 8 years. I know of only 3 field failures. The resistance of anything and everything changes with temperature. I'm not the electrics wiz though, my brother is.
