My mistake, the generic QFT feasture list includes all part numbers. Does yours have the: "....Adjustable by-pass jet for tuning low rpm fuel pressure or unrestricted by-pass"? It looked like one of the models had a carb jet screwed into the outlet and Im only guessing that it would alter the fuel pressure. QFT says its adjustable down to 1.5psi? The cheapo Mr Gasket fuel pressure regulator that I have was just a series of smaller holes and a knob so Im assuming the carb jet may have an impact on the pressure.
