If you find a fuel leak from the tank, it is recommended to replace the tank. If the fuel pump screen often gets clogged, remove and wash the tank
If you find a leak along the junction line of the upper and lower parts of the tank, you can solder these places (it is recommended to do this in specialized workshops).
To do this, pour out the remaining gasoline, thoroughly rinse and dry the tank. Then solder the leak with soft solder.
You can only solder a thoroughly washed and dried tank that does not contain gasoline vapors, otherwise the vapors may ignite during soldering.
