I got my aluminum tank from Evan Wilcox. Same basic price and you don't have to deal with shipping it half way around the world. I met him when he was making the bodywork for the prototype Victories and considered buying a bike just to have something I could put his stuff on. A bunch of years later I pulled the trigger for some Ducati bodywork.

I found these by googling "m16 barb fitting"
Have a look theres plenty of results to look through
