I once had a similiar problem and I had to have the hoses "custom made" because the OEM versions only came in one length.

Assuming that you live in a large enough city, look in your "Yellow Pages" for "rubber specialists" or "hose and belt specialists". These are companies that cater to industrial businesses like heavy equipment. They will tell you on the phone what they can do for you or steer you to the company you need to call.

I had to take my old hoses with me and they used the end fittings to make up the new hoses to the length I specified. They fabricated the new hoses while I waited.

I hope this helps.
