I am fighting this fuel guage problem. I did notice something today that may point us in the right direction to figuring it out. So I have 2 smartcraft guages and the fuel reading is stuck at 0. Today I turned my light switch to "both" and the fuel guage goes to 100%. That switch is a 3 way type switch with off/both/compartment as being the options. The fuel guage goes to 100 when I switch it to "both". Where should I start? Any suggestions would be appreciated. 2022 919
