They were completely blocked so i used a small diameter rod, i think stainless welding wire to free it up then went through it with a long pipe cleaner then had a competent welder seal the hole up and check it for leaks.
I think this is the best way to be 100% sure the tank will not give you any more problems.
Did you do anything to seal the freshly exposed surfaces inside? Won't it just corrode again if not?
