Tank is fine. That will clean your fuel system out. Be sure to change the fuel filter soon after as all the crap gets caught in there. That can cause the fuel pump to gum up like mine did. There is a filter element (basically a mesh housing) that surrounds the fuel pump. Over time, debris will get caught in it and cause your fuel pump to fail. Better later than sooner.
You can also disconnect the vacuum line on the intake manifold and suck it up into the intake and cylinder head that way, although it bypasses the injectors and goes straight to the intake/valves to clean the carbon off. Also, try some in your engine next oil change.
