The fuel tank has been removed and doesn’t seem too bad but had to cut one fuel pipe to remove it. Any advice on cleaning out and treating the inside would be appreciated. The fuel filler pipe will be a problem as the seal is not good and I understand isn’t available. The pockets are holed but repairable hopefully by someone with no experience of bodywork. But the small brackets just behind the wheel at the front of the wheel arch will be a problem. I’ll investigate a bit more over the next few days before I decide how to proceed.

Hi, and congrats for the project!
For the fuel tank, what i did on mine was, on the outside removed everything and went to the bare metal. After that primed with epoxy primer and then used some underbody treatment on it.
Internally i've used a product called Tankerite GUM.
Basically you have to first wash the inside with the provided acid, this will remove any possible rust inside.
Then you apply the tankerite following the guide.
This will leave the interior of the fuel tank covered with this hardener material that will prevent future rust and, if present, should also fill small holes.

About the filler neck, is rust the problem or is the plastic gasket at the base?
