Hello Jay,
And then a miracle happened...
The double sheave crank pulley is E7UZ-6A312-A
A single sheave pulley might have the number 4TZCA
Any one of these numbers could apply to a 1994 F250.
The reason for weasel-wording these numbers is that they come from 1-1/2 year old pencil notes which are a little hard to translate presently - sort of a paper-based Alzheimers
The double sheave water pump pulley is most likely E7TZ-8509-AC
Hope any of this helps!
Tom
