I know there are a lot of kits for do it yourselfers out there but I was just asked about cleaning and flushing a gas tank in an old 53 MG that I delivered last week. The fuel was old and I could see some rust flakes in the tank. I told him I would drain the fuel and look at the inside/ I guess there was flakes in it so he called the person I delivered it for to ask about a place. I said I would look into it as it might have to be sent out as I don't know anyone offering that service. It’s an exterior painted tank that’s it behind the spare tire. I was thinking maybe a Motorcycle place? Any help is appreciated.
