Did you replace the entire unit?

How much does it move?

It also could be a broken baffle in the tank.

You may have a broken baffle allowing the fuel to slosh around in the tank

Check your connections at the tank. Did you change the connector that was supplied with the module?

I got a new connector with the fuel pump. The fuel gauge was moving before I put a new one in. I was going to work when out of the blue it started moving and thats been about a year ago
