Lokar has in the past provided owners with a custom made. flexible, stainless steel braided hose/tube that is cut to final length by the owner.
They did this about 2003 for a PCNC member, and the Lokar rep was named Denver. He has since left Lokar, but I think others have found success with this solutions since his departure.
It looked great, was easy to install, was totally flexible and would be a good solution for your problem.
