By hooking up the boost reference on the regulated return you run the risk of over pressurizing the fuel system and causing harm to the injectors. The injectors like anything between 45 and 70. So, you would need your base pressure set to around 45psi with no boost. When you are at 20psi of boost, your fuel pressure will be at 65psi. Most (if not all) of the fuel pressure regulators have a 1:1 boost reference. You could get a Raptor pump and a tank sump. Set the regulated return to 65 and you shouldn't have but minimal fluctuation during WOT.

Im not saying I am going to do it, just wanted some more info on it.

If I were to do it that is what I would do. Set it at 45 or 50 with a 1:1 up to 65.

Its not high on the list, but is a possibility for when I get a pump and sump.
