Are any gunks or gunges practical?
We minimise the leak by running with only a small quantity of petrol in the
tank - my biggest concern is that the system doesn't pressurise as it
should and as a result the petrol pump is having to work harder.

You have to drop the tank and put Petseal or equivalent in it by
running it around inside the seam, which will involve a bit of
acrobatic work, but if it's just a seep from the seam Petseal will do
the job.
Check first that the tank isn't generally corroded.

That is good advice, I had one fall off just after i had filled up.
It was being dragged along the road by the pipe work.
The AA didn't worry too much when they towed me home after cutting the pipe.

But who grabbed the full tank and took it home?
