What’s up with my fuel gauge?

[Tenere Vols]

I’ve researched and read many concerns with the fuel gauge being off, but mine is waaaaaay off.  I bought my T7 used with an Acerbis tank. It would read low on fuel after about 150 miles of riding. I didn’t need or like the big tank so I went back to stock. Now it reads one bar and flashes after just 60 miles of riding. Any thoughts?  Do I need to pull the pump and bend the sender arm?

Thanks

Many owners of an Acerbis tank bend the arm of the fuel gauge without knowing what they are doing.

I guess you have to bend the arm back to it's original form.
