Thank you for help

If you have a fuel cell no problem getting the correct sending unit. If you still have the the factory gas tnak i would send the gauge back to be for one that works with Mopar ohm range.

Mopar is 10 to 70 as I recall The correct procedure and ohms range is in the service manual for your car.
