FAA AD 2022-03-15: Fuel Quantity Indicator
Is there any information on how this effects the RV-12 installation?

This doesn't affect the RV-12.
Only G3X installs in certificated aircraft are affected. In those cases, a 1K ohm resistor is inline with the fuel level sensor. This is to provide lightning protection (FAR 23.954).
Temperature apparently affects that resistor enough to show variations on the fuel level display. The AD doesn't seem to describe the fix, but I assume it will be to replace the fuel level sender with a newer version of it... (using a resistor that is more tolerant to temperature change).

This only applies to aircraft in which a G3X Touch was installed per the STC documentation.
Thanks,

It would be very helpfull for all of us to read the service documentation in order to understand how to solve the issue when a series resistor is installed. Can you provide this info ? Regards,
