Lost you on "additional pipe" (i.e. "tubing"). Most AC fittings can be removed and new rubber hose attached. I have done this on many cars. You can cut and peel off the thin crimped ferrule to get at the hose, using a hacksaw and/or cut-off wheel, screwdriver & pliers to pry. Some fittings are "Coll-O-Crimp" style where the ferrule is integral w/ the fitting, but are easily severed. Buy new "barrier" AC hose on ebay. I like "reduced barrier" for less bulk. If the 2 fittings are for different size hose, you can buy in-line adapters. If you don't have a Master-Cool crimper (like me) for new ferrules, use Oeticker stepless ear clamps for a clean look, or Breeze smooth screw clamps, if you don't mind semi-ugly. Even normal style screw-clamps (rugged AC-type w/ locating finger) work fine and were used for years in after-market installs.
