Fuel sender require recalibrating on a 2003 year?
Anyone know if new gauge and sending unit needs recalibrating on a 2003 year? Heard perhaps to fill boat and unplug battery but not sure if that is older boats or newer. Easy enough to do- I just installed gauge after new sending unit. New gauge tests ok by the pink/black wire test but doesn't read fuel with about half a tank. Any help appreciated!
