I don't know that that's true. The coolant side seal of the pump is
usually a carbon/ceramic face seal in "modern" pumps (modern meaning for
the last several decades). The outside seal is just to keep the grease in
and is usually a lip seal. The rubber could degrade with time, the
carbon/ceramic wouldn't. A problem I could see if is the drying coolant
left some crystalline deposits behind and they worked their way into the
face seal that could cause a leak.
I once got a TR8 water pump from a supplier that had clearly been on the
shelf for many years. I was a little worried about installing it, but did,
and it has worked trouble free for 10+ years. Of course it had never been
installed so not exactly your dilemma.
