We haven't prototyped the Senisis or Foggatti yet. Is it possible for you to measure the stock tanks with calipers? I can cross reference and see if we come up with a match. Will need OD/ID or wall thickness/length.
Update: They have the Senisis specs listed on the Senio website. It's 22 x 1.8 x 25. Unfortunately we don't have a match for that size.
cheers
surprises!
