If you have time to wait do an internet search for the correct size and pressure rating of the hose you need. I just did a quick search and found numerous suppliers.
If you need it quickly go to a large equipment supplier (Cat, John Deere, etc) that have repair facilities. Anyone of the larger suppliers should have the size you need. If you have the hose length, size of fitting they can make you up another hose. It is better to use a crimp type fitting on the end then a repair fitting which is normally screwed on.
If the hoses are routed fairly loosely you may be able to pull a hose replacement through. Get a male to male connector of the fitting size, remove both ends of the bad hose, connect the replacement with the male connector and try pulling through. Use some liquid soap to lubricate to make it easier to pull.
