If the damage is serious, a replacement is required.

To adjust the fuel level, turn the cover so that the floats are facing upward and set on a horizontal surface. The ball of the damper should be as much as possible drowned in the valve needle. It is important to monitor the clearances - they should be the same and approximately equal to 0.25 mm. In case of deviation with the help of bending the holders, it is possible to adjust the gap.
