No, it is on topic.
I would use interject Diesel Cure and Care, it is very powerful biocide additive. But, it might be a bit difficult for you to get, so the Fuel Doctor made by Castrol or Wynns makes additive with biocide, I saw at Sprint Autoparts for a very good price. Furthermore I would make sure that there is no rust inside the tank. Installing additional fuel filter with the glass bowl is good idea; Ryco sells one (around $60)

Check the fuel hoses, make sure they're not perished and that all the fuel connections are air tight. Also make sure that you have good compression, the valves could be partialy seized in valve guides. I worked on Triumph Herald a while ago, that was stopped for 10years and I had to remove the cylinder head, cause the valves were seized. The fuel tank was full of rust too.
