2. If the old hose is still usable, you can cut it at the kink and put a threaded insert on each end. Just be sure that the insert is the right size and not from the 99-cents store. Get a metal one. Or if you get plastic, buy 3-4 and take a radio with you so you can listen to the baseball game to keep you calm while you are breaking one after another or can't get one to stop leaking after working on it for 30 minutes.
3. They also make tube inserts that sometimes work. Or if you have some copper tubing around that fits snug inside the hose, you can connect with that with a couple of hose clamps.
4. And for the extry cheap feller not unlike myself... if the hose will stay open at the kink when it's straight, fasten something to the hose to act like a splint to keep that section from bending. Ideal is another length of hose that will bend slightly, or the hose could kink again near the ends of the splint.
5. After trying 2-4, go back to number 1.
