Can anyone recommend the best way to get the old bit out and suggest
how to repair/re-thread so I can use it again?

Thans.

Stud Extractor

Sadly stud extractors don't come with a maximum torque setting and I
have heard so many stories in broken extractors. In short unless the
item comes out with a minimal torque I wouldn't push my luck.

If the above fails or you don't have an extractor, being brass I would
drill this out, there's even a nice pilot hole for you.

With a correctly sized drill I've generally been able to pick the bits
of thread out, even in steel and then run a tap to clear the thread.

Most tanks have a drain, so you may be able to remove the fragments that
fall into the tank through that?
