As long as you are careful with the routing, you can run hose the whole way from the valve to the couplers, just watch for pinch points and sharp edges.There are 2 steel lines from the valve which lead to 2 rubber hoses then back to steel that runs under the left boom arm all the way to the front of the machine where the quick couplers are mounted to the left side of the boom cross brace. I think most of these components are not available. With the exception of the hoses, I think the steel lines would be pretty costly to have made but could be done by a hydraulic shop. Jeffco
