fuel pressure regulators
Ok so on the Ve fuel rail I noticed there are 2 fuel pressure regulators. I want to install my Nismo Fpr from my de will it fit? If it does fit which one do I remove the one on the passenger side or the one on the drivers side?

If you have the regular nismo reg it is a tight fit with one of the manifold braces. I slotted the holes in the brace so it could be pushed further out of the way or you could just notch the brace as others have done.

That is good to know. That's the crap I hate finding out about later when I am not expecting it.

My question now is which regulator is the fuel feed and which one is the fuel drain.

There is only one FPR and that is the one closest to the throttlebody. That will be your return to the tank.
The other unit you are seeing is a fuel damper and get mistaken for a FPR

Nighthog Would it be ok to do that? Would the manifold crack from the vibration or will it be fine?
