Hi Rightfully,
I think the tanks in the Deauville were very similar to the tanks in the Longchamp. If it is the small corrosion "pit-holes" problem that occurred with the alloy tanks I found a high grade epoxy was a good fix that has lasted many years. After removing the tanks from the car, I just cleaned the holes, fitted an aluminium pop-rivet into each hole (approx 2 per tank), then painted the outside of the complete tank with this very hard epoxy resin that was solvent resistant.
Just in case you can't find anyone to make some new ones.
