luv737s Posted July 16, 2017 Report Posted July 16, 2017 Left fuel gage shows full all the time when i know the tank is not full. I can tap on gage and it shows correct quantity but goes back to full. Because it shows the correct amount when I tap on it I suspect the sending unit is okay only the gage is faulty. Ideas? I stick my tanks every time I fly, so i know the exact quantity. Irritating to me though. Right tank shows normal. Gage repair?
Yetti Posted July 16, 2017 Report Posted July 16, 2017 Check for loose wire. loose ground. Corrosion on the gauge contacts.
carusoam Posted July 16, 2017 Report Posted July 16, 2017 +1 for oxidized connectors at the gauge. Don't forget to check the ground wire for the gauge collection... Best regards, -a- 1
