I have had a intermittent Fuel and water gauge.
As we know the voltage stabilizer is the culprit usually.
So not finding a spare in the "yard" and my last one was installed in my Green Rabbit.
Here is the replacement
Ka7810aetu from mouser @.78 cents each. 6 bucks or so to ship... but still less than one at Autohausaz or napa. Autohaus had the Fairchild part number on the web page....
I tried using the LM7810AC and it made my fuel gauge and water gauge read high... where I would of had to calibrate the gauges. So, the KA7810aetu is good for you.
What do Divorces, Great Coffee and Cars all have in common?
They all Start with good GROUNDS.
Replace all of them that you can, 99 percent of flakiness will disappear.
