I have no issues with my fuel pressure regulator, nor my pulsation dampener, but for preventative maintenance I'll be replacing my 33 year old injectors with new 12-hole injectors from OsideTiger (planning on this summer). While the intake and fuel rail are apart I was thinking it wouldn't hurt to replace the fuel pulsation damper and the fuel pressure regulator. The pulsation damper is still available, but I saw the regulator is not. This raises my question; is this a part that can go bad at all over 33 years and 320K+ miles, or should I just keep using it and run with it?
