Do these exist? I thought I remembered coming across a thread before that had a link to a company that would recreate your tank, but with plastic.

I originally wanted a fuel cell because I only fill up 5gal at a time for weight issues and I also want something baffled. But then I read up on fuel cells and realized they have all sorts of complications.

I just want to find a gas tank that will fill in the factory location and utilize factory lines/hardware/pump. But I want it to be lightweight.
