OSIAS Adjustable Aluminum FPR Fuel Pressure Regulator Kit +160 Psi Pressure Gage Universal AN6-6AN Fuel Line,Hose Fitting Connectors Kit

Fittings were of good quality and no leaks. Regulator seems to be of good quality and was free of debris. Looks identical to the aromotive regulator that I am replacing for a leaking diaphragm. I shall see if it lasts.

Installed with a ZZ6 EFI Crate engine that requires a vacuum connected pressure regulator. Easy adjustment and easy connecting to AN-6 fittings.

They would not publish my first review there was no profanity I just told it how it was !!this is not worth the money!!# I don't know if I just got a bad one but in the first 20 seconds the regulator diaphragm blew out . I had to spend $32 to get another diaphragm and wait two more days with my truck still down..before install I had to blowout almost half of a teaspoon of chips.all from inside where the diaphragm is.. I was a machinist for 15 years Step 1 in machining something blow the chips out I had to chase the threads with a tap on one of the holes this was just subpar all the way around I feel like I have more time And Machining and more money into it than it was worth.. just an honest opinion if you get it clean check all your threads and buy another diaphragm I will include a picture of the one I bought it was $30 ..the one this came with felt like a cheap latex balloon !!!held 40 lb of pressure for about 20 seconds and then out the top everything came this is the most disappointed I have ever been on any car part I have ever bought on Amazon !its not Amazon's fault !!but someone should check their quality control on these.. if I would have just put this on my Powerstroke and started it I would have had half a teaspoon of chips in my motor and injection system this was not my first one of these I'm sure it will not be my last but . it is what it is

Good quality unit for the price. ONLY problem is the fuel rail adaptor does NOT fit Subaru WRX. Other than that I am pleased with this purchase

Very easy to install and very simple to adjust.

Worked great

Did not work out of box. I’m giving this 3 stars because the fit and finish is decent and they send lots of fittings. But mostly because I have a feeling I could return this over and over until I get a working one. If you can’t afford to have a questionable regulator then do not buy. This would have left me stranded in the woods while off-road. It held pressure for 5 seconds then let go and no amount of adjustment will effect fuel pressure.

It’s nice and works good
