Well, I just installed my 440 injectors and took the car out for a spin. I am running the 2.72 disk with the hard spring....20psi idle fuel pressure and at 15psi I am only seeing ~50psi fuel pressure. I put the disk on top of the ring inside correct? I am not sure what is going on....any thoughts?

you put the disk on top of the ring, or inside it? Should be inside the ring..Using the 2.72 disk, the ring that fits should have around a 1/4" gap all around. For some reason thats the only disk where a ring doesnt fit perfectly around the disk. Vortech directly verified this.

Thanks Matt, I was using too small of a ring....everything is good now. :)
