OEM MOPAR Parts.

Don't confuse reproduction parts that are for sale by aftermarket suppliers (usually Chinese manufactured) with original equipment parts made by Mopar. Also. make sure the unit is grounded properly. A quick check is to take a lead with alligator clips on each end, connect on side to the tank and the other to the chassis of the car. Should eliminate a grounding problem with the sending unit.
