The gauge was on my bike when I bought it and has worked great for over a year now.

ISSUE: Yesterday it started blinking one LED is all, I assume low fuel but it’s full. Also all lights come back on when under full throttle so maybe only ride wide open? It does go back to blinking when you slow down.

Don’t flame me out I did a search first and need to check the wiring I guess. I did recently put a new battery in but don’t know why that would cause it.

 

Yeah I would suggest riding wide open all the time.. don't see any other solution that would work here..

 

The fuel was pushed back, the same way you were, when you opened up the throttle causing the float to go up. When you let off of the throttle, the fuel leveled out making the float go down.
