My fuel gauge never reads less than about a quarter tank, even when bone dry empty (ask me how I know that
). Now its getting worse as I ran out the other day and the needle was above the 1/4 left line. I checked the specs and the sending unit sends out 4Ω when full it should send out about 110Ω when empty. So reading always too full means it could be sending out LOWER than expected Ω readings. SO, I suspect its is not the sending unit as corrosion should mean MORE resistance, not less, but I will trace the wire and see if I can read it with a multimeter.
Than means that, if the wiring and the output of the rheostat in the sending unit check out, I should at least suspect the gauge. Anyone have these off and know if its a removable needle that I can just shift to the correct spot?
