ISX 2 different fuel pumps

[gag4o]

My friend gave me this fuel pump that he had forgotten about and sold the truck. My pump is 1.3 million miles and i believe it is the original. And since i have this one i would like to replace it.
You can see they are almost the same. The plate part on the left side is the only difference I think. By the look of it this triangular piece and the quater inch shiny plate comes out and then i can add that part from my original one.
Would this work?
