Review on 💪 Enhance Performance with the 0-140 PSI Universal Adjustable Fuel Pressure Regulator Kit With Gauge Hose in Sleek Black Design by Andy Hearshman

So far so good. The cover that holds the pressure adjustment can be rotated by removing the socket head screws to position the vacuum signal port to point towards the vacuum signal reference line. A plumbing diagram would be nice, but from other reviews I've gathered that the port opposite the gauge is the pressure side going to the fuel rail and the port opposite the pressure regulator (bottom) is the return. Also, the return requires a tee to connect the return from both the FPR and the fuel rail to connect it to the single return line that returns to the Ypur tank. The small vacuum port on top connects to your air intake as a vacuum pressure signal to make the FPR work. The FPR is set at 0psi, so you'll need to pressurize the fuel line by turning the wrench a few times and then set the fuel pressure to factory specs as a starting point. then press the button a few more times to ensure the pressure remains constant, adjust if necessary. The required fuel pressure in psi should be listed on your emissions label, but if not you can easily find it online. leaks. Otherwise it looks good and works as it should. But for €30 there is nothing to complain about.
