Re: fuel tank cleaning
On the 6 gal. tank, I removed the fuel pick-up assembly, and fill cap. Flush out the tank with hot soapy water. Hang a metal bar between the two tank openings using wire for a hanger, a piece of brasing rod works well. Use a wood dowl, or any good insulator across the tank openings to hang the wires on. Shake up a container of washing soda, "Arm & Hammer" about 4, or 5 tablespoons is enough. Pour it in the tank, and top of the tank with clear water. Hook a battery charger positive side to the wire hook, the negative side to the tank handle. That's it. In a few minutes you will see the water turn rusty.
