Abstract
A 3 fuel tank has a magnet 3 disposed on the inside or outside thereof in the vicinity of a fuel pump 12 which is housed inside the fuel tank. The magnet collects magnetic spatter which remains inside the fuel tank after welding and prevents the spatter from entering the fuel pump. The magnet may be a permanent magnet or an electromagnet, and it may be disposed outside the pump or in the fuel filter of the fuel pump. A cleaning method for a welded fuel tank comprises introducing a magnet into a fuel tank after welding, vibrating the fuel tank so that the magnet will move about the inside of the fuel tank and collect magnetic spatter, and then removing the magnet and spatter from the fuel tank.
