u/ExFLMan

Hello all! I’m on a couple week camping trip and after filling up today my fuel gauge is stuck at FULL. I’m not 100% sure yet, but the cruising range still appears to be accurate. I also put a diagnostic tool on it and was able to move the needle to all positions, but it goes back to FULL afterwards. Is a bad sending unit the likely culprit?? Thanks for any advice and insight!!
