Here's a good read. The bottom of the third page shows a return diagram with a regulator after the rails.

Yes returnless is in the tank.

Has anyone converted a returnless stock fuel rail into a return style with a AN fitting on the passenger side??

Would that even work?

Would be more effort than its worth, IMO.

Its recommended to always have the reg at the end on high hp setups so all the flow doesnt have to go through the regulator, only whats not used.

How are you currently regulating the pressure?

You can have always have your rails powder coated...

I just purchased a MagnaFuel MP9925-B for my new rail set-up.
I will be running it after the rails, just before the return.

I'm not regulating the pressure at all now. That's why I need to get my **** together and put rails on it. If possible, I would like to keep the stock fuel rail so I can keep the engine compartment clean. I like the fuel rail covers I have. But I don't know if it will function properly with the center crossover.

Here is a pic of the covers and rail.

Just thought I would update that I added an aeromotive fpr with a vacuum reference. I set fuel pressure with the engine off and the fuel pump running. Set it to 58 psi. Then hooked up the vacuum reference and started the motor. Looks like it idles around 47-49 psi.

Thanks guys

Ok so this is how you set up the FPR? I have the same one and just finnished my install of the fpr and rails. So after this idle issue should you adjust the psi to get it to 58 psi at idle?

You need to set the pressure at 58 psi with the vacuum line unplugged, engine off, and fuel pump on.
