I have the JDM B16a and my fuel pressure is reading 34PSI at idle and 44 at WOT. I have read that it suppose to be between 37-38 and 48 @ WOT.

Could someone let me know whats the correct press and the reason its so low on my car?

 

Are you having any problems? How old is the fuel filter?

 

I am guessing its there since the car was made.
