EFI fuel regulator

[Russ67Scode]

I have been looking thru the multitude of regulators trying to decide the best one to buy for my EFI FE build
I was looking to run -8N lines off both fuel rail ends and a -8 return back to the tank.  My supply side is a Aeromotive eliminator pump -10 line to a Y that splits to 2 -8 line to the fuel rails .  So as written the regulator is on the return side of the system, my first question is how big is the passage through the regulator? The oriface can't be 1/2 inch ? So do I really need the biggest regulator Aeromotive has ? I understand at idle the engine doesn't use much fuel and I will most likely get a pump controller to slow the pump down below 2000 rpm . But what are your thoughts ? What do you have on the Shelby Jay ? Pic looks like a A1000 ?

I've always used the A1000 regulator, although on my Mach 1 I used to use the A2000 because of the extra ports available for a nitrous system.  I don't know what size the orifice is but its pretty big.  When you see the amount of fuel pouring into the tank at idle from the bypass, you know its not some tiny little orifice.  I use #10 to feed from the tank, splitting to two #8 (one for each fuel rail), and a #8 line for the return.  I also use the Aeromotive Eliminator fuel pumps.

Thanks Jay,   Your system is exactly what I am building so I guess the A1000 will be ordered , Do you run a fuel pump controller ?  I don't think I will be sitting in stop and go traffic. So not sure if it would be worth it
Thanks again Russ

Currently I'm running the Aeromotive fuel pump controller.  But my new MS3-Pro EFI system has the ability to do the same thing as the Aeromotive unit, it just has to be programmed to flip a solid state relay on and off to control the pump.  The Aeromotive unit works well, though.  If you are going to run the pump continuously for more than 15 minutes or so I think the fuel pump controller is a good idea.

So does that mean you have a controller your not using and want to sell :-) LOL

No, I'm still using it until I get the MS3-Pro to take over.  Then I think I will save it as a spare for my Mach 1, which doesn't have an MS3-Pro.  Sorry Russ
