Fuel pressure regulator

I had one of the many that were sold in a large GB some time ago but it is no longer adjusting properly. I know many did not get installed.. anyone got one they want to get rid of?

I repaired the one I have for now but I am still open to buying another. I am talking about the Feng Hsing unit arranged by Pepe, by I am open to one of the Sard units that were also on a GB if I can adapt a gauge easily.

Sorry for the dumb question but why would an S2K need an aftermarket fuel pressure regulator? Wouldn't a VAFC do the same thing? Or does it do something different?

Good point, most of the time the fuel delivered is well controlled. It is my understanding that under WOT it is not the same, simply relying on a map and injectors / pressure withing spec. The stock FPR has a pretty wide range of normal pressures so when using an ECU that runs more lean it is prudent to know the pressure and adjust to the fatter part of the specification.
