Well, nearly two years later I still hadn't gotten around to replacing the sending unit. My fuel pump left me stranded the other day, so I reckon that was the motivation I needed. Two things: I had roughly 2/3 of a tank. I didn't want to drop the tank with that much gas, so I did the bed lift method. Although getting the 6 bolts out was tough (due to factory loc tite), that's the only way I'd ever do it again. Take 4 bolts out completely, and leave the 2 rearward most bolts about half way out. Prop up the front of the bed and get to work. Way easier than I imagined... Also, there were no Mopar fuel pumps in the vicinity, so I went with an Aeromotive pump from Autozone. Once installed, I filled the tank and reset to trip meter. When I get around 250 miles on the tank I'll throw a 5 gallon can of gas in the bed and run it down to nothing (or close to it if it seems to be working correctly). I'll report back if I have any issues with the Aeromotive pump. Thanks to all for the help above.
