Mine reads about like what is described here. 3/4 on gauge when full. Empty means you have like half a tank. Has anyone tried bending the arm to compensate? This sender was in the car when I got it, no idea where it came from. I’m guessing this car was gone through in the 00s.

My last car was pretty good, read 7/8 when full, empty was empty. It seems to have been rebuilt in the 90s
