🔧 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 Review

I really like this set because it comes with good fittings and the regulator was good quality and had a good gauge. J put it on my Jeep Cherokee

Reg works great just get another gauge, this one is very inaccurate. After fuel problems I bought another fuel rail sensor. The one that came in now reads 35psi and the other reads 55psi.

Easy to learn if you have mechanical experience, the bottom is bypass, the side with vacuum is the outlet and the other side is the fuel inlet, loosen the lock nut and screw it off the adjusting screw to decrease the pressure. I set it to 5psi on Holly, perfect. I like it.

I redone the fuel system on my 1994 K2500. It keeps the pressure where I need it for the TBI truck. I'm in the process of building a new port injected engine so we'll see how it performs at a higher PSI rating. In my experience higher PSI regulators don't work well at lower PSI and this one works well so I'm optimistic that 35 will work well.

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…
