You can buy a new oil cooler hose, or you can go to your local hydraulic hose supply company and ask them to make you one. Take in your old hose and they can either match up some new fittings or reuse your old ones.

 

I went to SEVERAL places in Houston, and NO ONE could make the lines. One place offered to cut the ends off of mine, weld them onto new barbs, and then make them from there. They also wanted to charge me $125 or higher to do it. Meanwhile he was griping about people who were saying they could get stuff on ebay a lot cheaper. Sounds like he needed a lesson in competition, and the real business world. Hey buddy wake up, it's not 1975 anymore, lol.,,,,BB
