I have a problem with Nitrous Installation. I cant find vacuum fuel pressure regulator. I find this in fuel system of 4G63. But I don't have the same on my 420A engine.
How can I provide fuel increase while nitrous is activated?

the only eclipse that has a fuel pressure regulator is the 95 the others 96-99 dont have one thats why they use wet kits.

That should read "the only cars that have a VACUUM INDEXED fuel pressure regulator are 95's." 96-99 have a regulator, but it's static at 50-something psi.

dino is correct. us 96-99 guys still have FPR, but they are back near the tank...not on the fuel rail. depending on what year you are makes a difference in what kit you need to use. if your 95 you can run a dry kit...but if your 96-99 you must run a wet kit...which injects additional fuel with the nitrous. people say that a wet kit is safer because you have less of a chance of leaning out

thank you, guys! you really help me.
