Question: Fuel Gauge only reads 3/4 full on a fill up

Usually a sign of a bad fuel tank sender unit, better to read inaccurate at that end of the scale than the bottom /empty part.

I had to change my sending unit. But if i don't turn the engine off at fill up it reads 3/4. if you turn it off and start back up it reads correctly.
