Best ways to clean out old fuel line debris from fuel tank?

[rwh963]

Craftsman version of Poulan CV 3400. Old fuel lines disintegrated
In the tank. Tried to flush out with fresh fuel, but didn’t do much. Don’t want to remove tank since I would have to remove flywheel.

Any effective ideas? Or just leave it in there.
