   original and stuck up into the trunk, but was a bolt on swop.  The only 
   modification needed was to weld an extension on to the fuel pick up
   that bolted into the top of the fuel tank - and adjust the fuel gauge
   "float" by trial and error.

   I purchased  the fuel tank from a local Alfa Romeo dealer, who presumably 
   got it from Alfa Romeo South Africa. Remember they had the only plant 
   outside of  Italy manufacturing Alfa's. Presumably they made them ( or had 
   them made )  in South Africa, as local requirements were a minimum of 65% 
   or 70%  local content. That meant  just about everything but the 
   engine and drive train was manufactured in South Africa.

   I don't know if the larger tank was offered as a factory option, as I 
purchased 
   the Berlina second hand, but doubt it, as there was no available fuel pick 
up,
   which I had to fabricate- as described above.
