6V to 12v Fuel Sending Unit?

[Kendog]

Next up is figuring out how to make my fuel gauge work. The truck had been converted to 12V by the PO, with the fuel unit not working, likely due to the voltage upgrade.

Presuming it's a 6V gauge, what 'step-down' resistor is used in-line to make it work? Or is it simply smarter to replace the sending unit and gauge with a 12V universal? NAPA was not sure what to specify/recommend.

Thank you, Ken

I was faced with this also some time ago.  Everyone I spoke with told me that the system voltage makes no difference at all with the fuel gauge or sending unit.  The important factor to consider is that the Ohms rating of both components is within the same range so as to be compatible with one another.  You might find that the bulb in the gauge would need to be correct for your voltage, however.  I'm sure that others here can give you more information but this is what I was told.
