I need some advise on what fuel pressure regulator is right for my set up, I have

To4b turbo
Stock port TURBO II engine
Microtech lt12s W WB
Kd parts primary and secondary fuel rails
880cc x 4 precision injectors
-8an/1/2 inch fuel line


Now I do I need a fuel pressure regulator with 4 ports or a 2 port.
I am trying to use a stock FD fuel pump and a stock turbo II fuel pump both in tank, any subjections

 

I use an AEM Universal with the parallel fuel mod. 2 inputs and one return to the tank.

 

You can use whichever one you want, they are -essentially- all the same. Make sure as mentioned if you're doing a parallel fuel mod that you have one with to inlets.

I use a turbosmart, but you can use an AEM, Aeromotive, the list is endless.
