Being no stranger to the Concours I got an variable resistor and installed it in the gauge sender line. The connection is an old Tammy plug in & the resistor just didn't do its thing anymore so I swapped out the resistor.
Anyway, the best I can get is the guage says full when full, says about half after 50 miles and will sit on the red line for another 60 or so then run out of gas (switch to reserve). I can't seem to get it more precise than that.
So has anyone had better results taking the tank apart and adjusting the internal float? Any ideas on the angle of adjustment? It would be a bear to adjust, fill, empty, adjust, fill.......
I am certain I would end up starting a fire.
Thanks
