CAT equipment dealers can make any hose, on site while you wait almost 7 days a week.. with just about any pressure rating and any type of fitting.
not real cheap, no... but they do make them and time is money.
of course it's not a Cat part, and they will have to actually see it to make you a replacement. You may have to be a little insistent that you know what you need and know what your doing. (I'm sure you can handle that)
you'll do well to say you want it in XT3es (3000 psi hose) you probably have JIC fittings.
