Hey all!
I'm currently in the process of plumbing my fuel system and am planning on running a Series 3 Returnless fuel rail. Does anyone know if the Corvette / LS Fuel pressure regulator combo will work for this application (I find mixed opinions on this)? How will tuning need to be set up? This is a brand new rebuild so I can't dyno it to get it dialed in, I need to have the fueling somewhat accurate from the get-go in order to properly break in the engine.
I'm really stuck at this part, and any help would be appreciated!
Thanks![This message has been edited by Akasa (edited 02-03-2021).]

The fuel pressure needs to rise on boost, this is accomplished via a variable vacuum/pressure signal.
Does this pump have that capability?

I don't believe this regulator does, it's a fixed (constant) 58 PSI unit.

On the single fuel line series III 3800SC the setup is easy. You use a 2 bar rising rate fuel pressure regulator, and the return is made by using a simple T on the return side with the FPR sending excessive pressure back to the tank. ------------------ " THE BLACK PARALYZER" -87GT 3800SC Series III engine, custom ZZP /Frozen Boost Intercooler setup, 3.4" Pulley, Northstar TB, LS1 MAF, 3" Spintech/Hedman Exhaust, P-log Manifold, Autolite 104's, MSD wires, Custom CAI, 4T65eHD w. custom axles, Champion Radiator, S10 Brake Booster, HP Tuners VCM Suite.
