I need help. A hydraulic line has failed. I have a 2021 3781RL. The hydraulic line located just above the yellow fill cap failed just next to the crimped on end. It is 22’ long. Not sure where it goes. I attempted to replace the end with a Parker screw on end and as you can see in the picture the inner tube is too brittle and failed as well. Can someone tell me where this line goes to? Is it possible to tie a new hose to the old one and feed it in while pulling out the bad hose? Suggestions are welcome. I have until Tuesday, August 27 to fix it.
