This makes it sound like the part in question could have been easily replaced. The assembly in this case was the seal pack that isn't intended to be serviced. Even if they could have ordered the plastic coolant line, the removal and tear down of the pack to replace the line would have been a tremendous effort. It's debatable that it would have been easier to replace the pack AND then part out the old pack. The plastic coolant tube should have ended at the pack housing with a threaded insert and the tap should have just threaded into it. If pack had been designed in this manner, the repair would have been trivial. The pack is has a severe design flaw in my opinion.
