Hey, well i've been getting some notes from other members that an ajustable fuel pressure regulator would be me answer to my problem with my 2000 civic EX, can anyone back this up or give me some info about it (maybe even how to install it)..

I'm no expert but I don't think it will. May be your FPR is bad and a new one isall you need.

I have a 92 Si Civic our FPR sets on the end of our fuel rail

On an OEM set up the FPR is usally on the front top side of the fuel rail. There are easy to change. Not sure where your is. What engine do you have.

If your running rich and the tune is correct then yes it could be the FPR.

I don't know enough about your setup or problems.

Fix the problem that's causing you to run rich.

An adjustable fpr is no good for tuning because the fuel demand is not linear. An adjustable fpr is a bandaid for people running at the upper limit of their fuel pump and/or injectors.

in my cousins car his CE light was on due to runnih to lean. put a fpr that was laying around in and adjusted it and the engine light went away and runs good.

was your FPR a stock one or a aftermarket adjustable FPR?

my FPR is stock so would i just need to buy a new stock FPR or buy a aftermarket adjustable FPR?
