Hi Raymond, From your description your current hose is probably PVC. PVC is naturally quite hard but plasticizers are added to make it flexible. Over time those plasticizers break down and are dissolved by oils so the plastic hardens.
Urethane should be fine. It would probably be my choice in your situation. Fuel line would also work but you need to be aware that with most fuel lines only the inner is rated for fuel exposure. The sheath is often a different rubber which is not rated for continuous immersion. Another possibility would be hydraulic return hose. It is tough and resistant to most hydrocarbons. The down side is that it tends to be heavy and quite stiff.
