fuel pressure regulator

Hi does anyone know the part number of the HRC fuel pressure regulator? and even better where I could obtain one? After obtaining a set of HRC injectors I'm now struggling to increase the fuel pressure to 57 PSI.

Unobtainium........the HRC parts hoarders are gts455 and Subsailor may chime in

You may try that other forum too, speedzilla.

Good luck!

Unless they are buried in a warehouse somewhere in the world (it's possible), they are long gone.

I would look around for an aftermarket one or better yet, make one myself with an adjustable screw and a spring, calibrating it with a pressure measuring gauge.

Did you check if CBR 1k fits? Then the CBR's HRC FPR should work as well

Hi Guys thanks for your help. have managed to modify the standard unit by deforming the diaphragm housing with the end of button head screw. deformed it by approx. 1mm and now have just under 60 psi.
