The tube is not part of the water pump. In fact, if you look in the service manual it tells you to "remove the 2 coolant tube bolts" prior to removing the water pump.
Now technically, you very well may be correct that there is an O-ring (has to be either O-ring or gasket), but this stupid steel tube is attached to the outlet of the water pump on one end (where the gasket goes), then to the engine side of the lower radiator hose. I see absolutely ZERO reason for this tube to exist in the first place. It does nothing except allow for another spot to leak or rust thru.
It is maybe 8-10" long and slightly curved. I have not even been able to find the tube itself listed on Fords site.
If you have a Clymer SD manual, there is actually a photo of it in the coolant/water pump section.
