My truck is a 2020 3500 with the 6.4 Hemi. Could someone take a look at the pic I attached and tell me if that piece of black tape is on their truck also? Its located on the small A/C line (high side?) coming up from the compressor just below the oil dipstick. I've had A/C trouble like so many on here and had it to the dealer once. They said there wasn't any refrigerant in the system at all so I asked them where the leak was then and they said they couldn't find one. I thought I would look around to see what maybe I could find and this piece of tape doesn't look like any other under the hood. It also looks like the line may be dented the way the tape is shaped. Warranty is running out soon and just want this thing fixed. Thanks guys
