Pour tap water into the tank. Move the tank into the flushing area (wash rack). Agitate the water vigorously. Drain the tank. Pour the gasoline emulsifying agent into the tank. Use an available emulsifying agent. Add water to the fuel tank. Refer to the emulsifying agent specifications for the mixture ratio. Agitate the mixture for ten minutes. Drain the tank completely. Fill the tank with water until the tank overflows. Completely flush out any remaining mixture. Drain the fuel tank. Use an explosion meter (if available) in order to check for a negative reading. Perform the required service work. Repair the fuel tank. Installation Procedure Fuel Tank Purging 1. Inspect the tank for any remaining fuel. 2. Pour tap water into the tank.
