You said you "Decided to get the original vacuum tank Working properly". Why do you need another fuel system as well ? So many cars used vacuum tanks for so many years ,Yet with todays technology we need redundant system ? That's too nice a car to mess with an electric pump. It just needs nothing more. As for tubing, what was there ? Steel will out live us both, copper too if you want the easiest and quickest way. Great auto, I saw it at Stan Hywet.
