    I have a boat with a built in fuel tank and the only access is the sending unit hole.  Fuel has been in the tank for years. What is the best way to clean the tank? 
    Thanks :D

    Sorry man, but I no longer own boats with built in tanks. That way if I ever have a concern about junk in the tank I just throw it away.

    I would think a mechanical pump/siphon stuffed in there would get most of the old out. Then put some new in and slosh around and then drain again.

    There are mechanics on here that would probably have more knowledge than I, but I am sure it is still not an easy task.
