Can anybody help, I just installed a new Stuart Warner float type fuel sender my right fuel tank (standard Vans sender), connected to a recently installed Garmin G3X display during flight the fuel indicator on the Garmin display keeps jumping between the correct amount of fuel (approximately 8 gallons) , to full tank which not the correct reading. I have removed the float sensor and tested it with jumper leads going to the wing wiring, and it works fine, but some how when I reinstall it it goes back to erroneous full tank readings.
