Jack,
You could cut corners by getting a 1.5 " double threaded male coupling for the pump. Take your old hose with you to the shop, and get the new hose. Ensure the male end of your old hose is the same size as the new male and female end. The female end of the new hose MUST turn independently of the hose itself. Put the new threaded coupling in your pump, then the male end of your new hose on the steering, next just put together the female end on the coupling you just added to the pump. OR..try a different parts shop.
