I have a little over 200hrs on the original Princeton capacitive senders in my RV-7. I have been very happy with there accuracy and the fuel level readings were fairly close compared to red cube until just recently. Now, consistently on the last few tank fill ups, the readings will go back up to 21gal per tank when fuel is added, but don't go down very much as fuel is used, e.g. only a decrease of 1 gallon is shown (either tank) when several gallons have actually been used from a tank. I was getting ready to recalibrate, but both tanks act the same way so I was thinking it may be more of a system issue/software since both tanks started doing this? Has anybody else had similar issue and what fixed it? I’m using the complete Garmin G3X touch suite of avionics and engine monitor.
I believe these were the 5pt Princeton capacitive sensors from memory.. Again, they were working fine until recently and I can't tie this event to anything else that has changed. I use only 100LL. Thanks in advance for any ideas or your experience.
