Took her into the dealership on Tuesday and they diagnosed the problem to be the sending unit(s). Didn't have them in stock so I expected to have her back maybe Thursday or Friday.
Received a call Thursday that upon installing the new sending unit they noticed the baffle floating around in the gas tank. They ordered a new tank and said they'd have to remove the rear suspension, rear end, Ark Grip, and driveshaft just to drop the tank and replace it.
Expecting to be without her for another week.
On the bright side at least it is still under warranty.
