Thank you again to all that contribute to this resource. I was having the same problem with my 2017 Cougar FTD port tank not reading. Since I have smart craft gauges, and it was inop as well, it seemed logical that it was the connectors or the sender. I visually checked the butt connectors. No corrosion and a good pull on the wires showed a solid crimp. I was just about ready to order a sending unit when I read the post by shef1. I thought what the heck, I cut the butt connectors out, twisted the wires together and wouldn’t ya know. It worked!
