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

This is NOT a fuel pressure regulator! mechanical adjustment and vacuum do not reduce idle pressure. If you adjust the pressure at idle with the vacuum off, the pressure will not be adjusted when you turn the vacuum back on. I set it at 48psi and it stays at 48 from idle to WOT. Fuel lines and clamps are so cheap they're dangerous. Do not use the supplied clamps and fuel lines! If all you want is constant fuel pressure, this will work. If you are looking for something that regulates fuel pressure, this will NOT work.
