@Daljit SinghI would just remove the tank.Empty it of fuel.Force air into it and vent from the top until the tank is dry.You could fill it with TSP and water, air dry it again, and cut it up with a Sawzall for scrap.Or sure, you can get a professional involved that could run you some big bucks.Fuel tanks don't scare me.
