Hello and welcome to JustAnswer!
There isn't a published specification for fuel sender resistance. The best way to check it's operation is by monitoring it's signal on a scan tool as it is moved. If it was replaced and especially with a Mopar part I wouldn't expect an issue with the sender.
The gauge dropping is most likely going to be a fuel transfer issue but could also be software related or the sender physically getting stuck. If fuel isn't transferring due to a pinched, kinked, or disconnected line then it will cause this.
One of the most common causes of this was a sender getting hung up on something in the tank, usually misrouted lines or wiring between the two pumps.
