I bought electronic gauges and replaced the fuel sending unit on my 1987 Fiero GT 6 cylinder.

The gauge bounces around a lot and is not accurate.

Anyone has this problem and fixed it?

Thanks!

Did it work properly before assembly into the tank?

Does the gauge bounce around when the car is not moving?

I installed an electronic gauge and when I installed an electronic gauge the numbers started to bounce around. So then I replaced the fuel sender unit and still the same problem.
