TOMEI TYPE-S ADJUSTABLE FUEL PRESSURE REGULATOR INSTALL

After installing the bigger fuel pump, I thought it was a good idea to add an adjustable fuel pressure regulator in case I needed to alter the fuel. Since I am still operating on stock ECU, I do not have any other way to alter fuel. The Tomei Type-S is a nice looking unit so I decided to go with it.

Questions my friend how you control the fuel pressure that going to the injectors if you connected the fuel pressure regulator after the injectors you can adjust the pressure if connected between the pump and injectors i dont sure about this i just wondering thank you

Hey! This is a great question. The FPR is connected after the fuel rail so that all fuel going to the injectors and rail is constant. Once the PFR pressurizes the system after it leaves the rail, it pushed back into the tank which in turn adds the pressure to the new fuel gong to the rail/injectors. Hope this makes sense and answers your question.

@@Morm1175 I have also a 300ZX (Z31) and I still don't know why this model has the fuel pressure regulator BEFORE injectors, I made this question to many other mechanics and I still don't have any answer to this.
