well i have removed the old sending units and have determined they are bad. Unit reads at full and at empty, no in between. I remove the unit and bench tested it along with having it removed from the tank and with wires connected confirmed with the gauge.
I see the part number on the sending unit, but my when i googled it, i got several units with that same part number yet different ohms.
How do i determine the ohms of what i need?
