As (relatively) inexpensive as tanks are, I don't think it's worth it to clean them up and re-coat the interior. 

That said, you really should replace the hoses and crossover tube to prevent future problems (overflowing at the pump for example).

The usual list venders can supply fuel tanks and kits for the hoses/grommets/fittings for the items above the tank.
