To increase the knowledge base here the Ford Part No. for the liquid hose, 3.0L MTX is E9DZ-19835-A. I've been told, although am not certain that the part no. for the 3.2 is F3DZ-19835D-A. Both are obselete but there's still a few lingering on shelves somewhere. Motorcraft O-rings should be YF982.
Because I wanted to avoid fitment issues I went with the Ford part from a NOS supplier which sold at below list, $29.79. They go from some suppliers for about $60.00. Hopefully when I get it it's the right part!
The information you've given got me on the right track so I thank you agaim
