If you look back at post #65, there was a large hole to fill in the trunk floor side panel around the fuel inlet pipe.
Solution was to make up a split panel to close it up adequately. Here's what it looks like now:
I haven't grommeted it 'cos I don't have a large enough grommet, and anyway, there is no relative movement between the inlet and the split panel so close to the tank.
I'm waiting on a large enough P-clamp to better secure the breather pipe to finish off the job.
Cheers,
Glen
