V6 and Zetec fuel pump / sender unit the same?

I bought these for S97 s while back but never used either obviously. I tested both for output and one was better than the other, so thats yours if you want it mate. I'll get a piccy tomorrow. Is it just the sender you need or pump/sender complete?
 
Whole thing I think, I'll pull the seat tomorrow and see which type it is (outwardly anyway)

The two you have - one early one with coloured clips and one late one with black clips?
