I know the sho guys, just use mustang fuel pumps, so I imagine we could do the same thing. At least thats what I'm planning on is 155-190lph pump. Let me know what you find out!
I'm not sure about the return style fuel system(which you have), but for returnless, walbro pumps work with some modification to the pump housing. I'm almost sure they can be made to work for the return style. SPmotorsports sell the walbro pumps. They might be able to tell you. Try searching also on CEG. I know this subject has been covered a few times in the forums.
