I just got a 93 rx7 and I'm trying to install a adjustable fuel pressure regulator, can someone tell me where the stock FPR is located? I thought it was on top of the engine ins the front but I don't see it, hope its not in the back of the motor

 

Download the Factory Service Manual (FSM) if you haven't yet from the sticky threads at the top of this forum.

It's located on the secondary fuel rail on the firewall side. Follow the fuel lines.

 

Got it installed today thanks. Do you know the stock fuel pressure at idle on a FD by any chance?

 

With vacuum line removed from FPR it is 40 psi.
