I have a Harley Davidson Performance Combination Speedometer/Tachometer KMH # 70900071A Gauge, and have had it on my bike for around 8 years and everything has worked great but, recently the fuel level indicator bars have been stuck on Half way even with a full tank.
The low fuel indicator light icon does still work.
I also have a flush tank mount kuryakyn Fuel/Battery gauge and the fuel level indicator light bars work fine and show a full tank, when full, and lowers as i use fuel accordingly so all good there so, I know it's not the fuel level sender unit float getting or being stuck.
Does anyone have any ideas as to why my Harley Davidson Speedometer/Tachometer gauge # 70900071A fuel level indicator bars would be stuck on Half way

First step would be to pull the sending unit and check the resistance range with a VOM.

You're electrical diagnostics manual should have the correct range for your bike.

Might be getting varnished up. Ford actually sells an additive to add to the gas to clean up the sending unit.
