I'm not sure. As a rule, I don't trust the gauge, so I do a visual of the fuel tank from the aft end.Roleur,
Is your fuel gauge accurate. Mine is not and after calling the gauge manufacture there is no calibration. Mine read empty when there is about 4 gallons left.
From the manufacture "The gauge part number 301-010-002 is 10-180 ohms and is not adjustable. Only the fuel gauge for the 90-0 ohm tube type sending unit is adjustable."
