You should be OK using rubber hose and clamps. To be on the safe side, use rubber hose that is designed for fuel injections systems -- they're designed to hold higher pressure.

If you want to be really slick, remove the metal tube and have a buddy weld the leak closed (it it's steel) or silver solder it (if's it's brass or copper). Make sure you wrap a piece of hose or inner tubing around the metal tubing where it is clamped to anything, in order to prevent an abraded leak in the future.
