So i'm 99% sure my fuel pressure regulator is garbage.
I did a fuel pressure check on the fuel in-line after the fuel filter and got a reading of 47psi while idling and gassing it. no bueno

I was looking at getting a Megan Racing Fuel Pressure Regulator^ but when reading the description I noticed it says, "NOT A RISING-RATE REGULATOR."
That tripped me out bc i'm not sure what kind the stock fpr is.
From my understanding the stock fpr is supposed to be at 34psi while idling and 42psi while on the gas. (for many reasons)
My concern is whether or not the new fpr will work the same way.
As you can imagine with my fpr running at 47psi, my car is running rich, and ill tell ya'll its not helping my gas millage.
On top of that i'm getting fumes in my car which makes me think twice about lighting a cig in my car and makes me feel like I need to nap all the time. lol
So can some one please enlighten me.
I'm wanna get this problem fixed as soon as possible for obvious reasons.
Thanks for looking, and commenting.

P.S. My engine is an S13 ka24de. Just in case that bit of info can throw one off.
