Well I wish I would have known I have one of the biggest fuel pumps in the Norhtstar family. I did some research and found out the others years and vins that are interchangeable with an E8785 or aka 6443546. This site helped me if anybody needs this info: efuelpumps,com
You might also try www.rockauto.com, surf through adjacent years to bounce part numbers off each other.

Consider that, if the fuel pump itself is bad, give some thought to replacing the whole module - pump, fuel level sender, and tank pressure sensor - as a unit. While you're at it, check the fuel pressure regulator on the fuel rail - that will play hob with injector pressures and rich mixtures.
