I'm doing a 04 Cobra swap into my 96 Cobra (Everything but the fuel stuff), and wanted to keep my tank, lines, and I have a custom 96 fuel rail (buying one) that fits the 04 intake. I'm just running one 320lph fuel pump, which is plenty for my setup. I was wondering how I would power the FP this way, and then I found this post. I really hope this works for my setup.
I don't see why it wouldn't. Simply use the FPDM to trigger your single fuel pump how its explained in the first post of this thread.
