From the Auto Forum:
My brother and I have a problem: we decided to pour a carburetor cleaner into the tank. And when it was poured, a stopping ring fell from the throat of the bubble into the tank. It is plastic, it will probably use gasoline!!! First we tried to get him by a bicycle spark, but it turned out to be short and we accidentally dropped it into the tank. Then they tried to get the spit with the help of a magnet: they took a larger magnet and dropped it into the throat of the tank. But they didn’t think and the magnet clung to the wall of the tank from the inside. They began to shake, and the beetle soaked and rubbed around the magnet’s edge. He also stayed in the gasoline tank. In order to pull out at least a magnet, they took the largest key that had ever been able to climb into the throat in the hope that it would catch the magnet. The rope was thick. But it turned out to be synthetic, and while we caught the magnet, gasoline turned it off.
So now in the gas tank lies a ring, a magnet, a spearhead and a gauge key.
Tell me how to get it all out of there.
