The way we typically run them is 1 relay per pump....but all pumps behind the same fuse.I usually put all new relays near the bulk head and run new wires because we are almost always adding an additional pump so having everything in one place simplifies the troubleshooting process and just looks cleaner. From looking over the wiring diagram I don't see a reason that your idea wouldn't work. I would check the wire gauge to make sure that you can safely pull enough amps for the E85 pump and make sure that the fuse will hold. If you try this please let me know how it works. I have never gone to a 4E85 pump and kept the stock FPR so I don't know. I think it would depend on the fuel and the power level. E85 at + hi boost application might over work it....I just don't know. Might run this part by on of the tuners.
