That's good.
If it's from the rad to the tank, then that's the top vent pipe. It's job is to pass a small amount of coolant to the top of the tank, taking any air in the system with it. Which end has broken, the radiator end or the tank end? That plastic pipe goes very brittle with age, so it's actually best to remove it and replace it with a suitable length of standard rubber coolant pipe. If it's broken at the rad end, then you'll need to remove the from bumper, so you can access the radiator which is hidden behind.
[/its not hat one it's the main hose from radiator which is fed from tank that's gone. Turns across bulkhead and t's off at engine then goes across front of radiator to road itself.
