Shmoo, thank you for the feedback, I'll try to update the diagram.

Basically what is going to set this unit apart from any other fuel pressure regulator currently on the market (or for the next 20 years due to a patent) for Honda/Acura are the following:

1) small enough as a 12:1 regulator to bolt straight onto the fuel rail using the factory fuel connections, so you don't have potential fuel leaks and carBQ's

2) Absolutely no diaphragm, so it is very responsive to boost and all transitions from vacuum. And for the NOS guys, tough enough to get hit straight with NOS, like a wet system without plumbing for wet jets.

In the end this regulator will be the first and last regulator a Honda/Acura owner will ever have to buy. From using 1:1 ratio with intake/exhaust/cams, then 12:1 with low boost, and then using it to fine tune Standalone like EMS. One investment, that will follow your project's progress.
