There are a couple of oil lines that go through the casting under the fuel tank. Open the side screens and remove the flat covers around the hydraulic pump. There is likely a bunch of dirt filling the compatment. Clean it all out. Then look at the oil lines. They are hard to see. I think you may even see them from below the frame. These are steering lines and may not leak if not used.
