Hi there,

I am having a problem with the anti-surge box in the fuel tank in my car, the box keeps turning after every couple of tank cycles (as in filling the car up with fuel and using that petrol before filling it up again) and fouling on the sender so that after just below half tank the sender float can't go all the way down because the anti-surge box has moved.

Is there any way to tighten this thing down without having to rip the thing out?
