Fuel level - cause?

I've owned my e46 330ci for 2.5years now, and this is the 5th time I have had to replace the fuel level sensor!

Does anyone know what causes these to break?
every time it has been the circuit board that has snapped in half.

Can you see anything in the tank when you install them? Are you putting them in correctly? Parts snapping indicates that something is hitting it that shouldn't, either during install or while it's in the tank.
