I think he talking about these that are round washers in the bags in middle of pic
That is the port for the tubes. There is a square cut out of the shroud where that will be installed so that there isn't a large hole in the shroud.
The installation guide should have all of the information, as I have read it, (even though I have never owned a hybrid) and it gave pretty clear instructions.
This will be better:

As for the washers, I would think that would be for the waterpump, as that would be the easiest place. To scratch the PCB. They would reduce the chance of scratching.
