O.K.. I see from the following press release that the tanks are contracted to Alcatel Alenia Space in Turin, Italy.
Alcatel Alenia Space (probably just Alenia Spazio then) won this work in 2001. The move from Pueblo didn't happen until several years after that. Who built the tanks prior to 2001?

Answering my own question (the answer is Boeing at Huntington Beach), with info from the following abandoned web page.http://22.214.171.124/search?q=cache:i5wdqt70wkUJ:www.alespazio.it/space_infrastructures_page.aspx%3FIdProg%3D43+%22delta+II%22+tank&hl=en&lr=&strip=1
"Since the 1980s, and exploiting the know-how and technological capabilities deriving from aeronautic and space applications of Tungsten (TIG) welding, Alenia Spazio has developed a production line of a small series of tanks in special steels for the liquid propellant of expendable launchers. With the termination of the medium European launcher Ariane IV, for which the company delivered 482 tanks over a period of 20 years, Alenia Spazio is continuing the production line through a major commercial contract with the US company Boeing for the tanks of the Delta II launcher. Alenia Spazio produces the (single) tank for the second stage which was previously (up until 2002) built at Boeing in Huntingdon Beach, California. The present contract (a unique case of a non-US company working on an American launcher) is for the supply of 22 tanks. However, given the long life expectancy of the vehicle, there is a strong possibility for other orders in the future. Tank production began at the end of 2002 after a successful development and qualification phase and 6 tanks have so far been delivered."
