But in Cincinnati here there is a place...I think its called "Ohio Hydraulics", they are a hydraulic hose job-shop. counter service too =)
They had a selection of various kinda of hoses (from coolant, to air to hydraulic hoses (think bobcat and industrial hydraulic applications
One hose matched very nicely the diameter and pressure/temp/oil ratings suitable for 617 oil cooler hose. that hose would kinda be overkill for you(maybe?) but see if there is a hydraulic hose shop/distributor in your area, call around to find one w/ counter service (I took my two fittings in [the factory oil cooler hose was dissolving] and about 30 mins later I walked out with a 'good as new' hose with properly crimped connectors and everything ready to bolt back up.
