My sending unit/gauge reads just like yours does. A few weeks ago I drained the tank and tested the sending unit with the ohm meter and it read close to the previous post (09-76) . I bent the sending unit arm until the gauge read full when the sending unit was forced to full, and read empty when the sender was forced to the empty position. After reinstalling and filling the tank one gallon at a time and recording the gauge position after each gallon, it wasn't any better. Tonight I ran out of gas on the way home (near a station...whew!) so tomorrow I'm going to repeat the drill. This time I'm going to bend the arm so the gauge reads past full so maybe it will read correctly once reinstalled. I don't like it only going to 3/4 when full and not knowing how much fuel is in the tank when on E. I'll report back tomorrow after the job is complete.
