Review on 🔧 OSIAS Universal Aluminium Adjustable EFI Fuel Pressure Regulator Bypass Return Kit +160 Psi Pressure Gage AN6-6AN ORB Fitting Connectors Kit Black & Red: Optimal Fuel System Control and Monitoring Solution by Brian Cox

I love the price and have all the fittings, the only problem is that the sensor sometimes seems to be off but this has not been confirmed. I simply adjusted the base fuel pressure to 50psi and so far it has fueled my NA engine with no issues. With the help of the regulator I lead fuel from the 340 l/h intake pump -6AN into the return line. Connected to a 14 volt DC relay using the factory fuel pump relay signal. The pressure regulator works great, just test it before use. The fit and fittings are burr free, ensuring everything is tight. Don't want leaks. Works but if you can afford a brand name get a brand name, you don't want fuel issues with an inbuilt motor. Maybe use for a short time. If you're on a budget, you get what you pay for. I will buy it again for sure, will use it again. definitely recommended
