Default Drag Specialties LED fuel gauge

Anyone have any experience with the Specialties LED fuel gauge ? I bought one for reasons. My tank is currently empty, the OEM gauge and the speedo gauge both show E. With the DS fuel gauge is shows empty and my Speedo shows 3/4 tank.

Here's some tech info on the fuel sender in your bike p/n 75219-09.
Perhaps you could try to check the values with an ohm meter to find out is the sender is doing it's job properly.

The Electrical Diagnostic Manual states on page 4-20 Full = 27-40 ohms...Half-full = 97-118 ohms...Empty = 240-264 ohms...

thanks for the info, when I swap back to the OEM gauge everything works as expected. I reached out to Drag Spec yesterday for some help. Someone must have pissed in the tech's cheerios that I talked with because he was in a pissy mood. I will probably end up writing this off as a lesson learned and avoid Drag Specialties in the future.
