You dont need the stock FPR. Your diagram is little confusing.

Scott,

You should add a fuel pressure gauge at the AFPR. So when u tune your car, you can see what is the fuel pressure at all time. For my FI LS400, I have it at 38 psi with 460 cc injectors along with the upgrade Walbro fuel pump.

Yeah, I have a gauge. Interestingly I was told the book spec for WOT fuel pressure was 38-42 psi or 38-44 PSI, I forgot which one. I would have thought you would be running on the higher end. When I was dynoing, we saw fuel pressusers of 41 PSI on my car. I am also going to run a Hobbs Safety Switch.
