EFI Fuel Pressure Regulator Kit with Bypass Return 0-100psi Pressure Gauge AN6-6AN Fuel Line Hose Fitting Connectors Kit Adjustable Universal Aluminum Black & Red

Good sturdy product, was an easy install nice fit only 1 of the links broke and leaked but was able to use from the extra links so all good, able to handle the 4bar i needed functions awesome.

Looks nice but doesn't work or adjust pressure at all. Leaking fuel no instructions. Do not recommend this particular part!

I got it all in my 89 pick up carb swap. The gauge was leaking fuel. I was not so happy. But they sent me a new one 2 days later and I just had to send the old one back with in 30 days. Very satisfied with end result and product. It looks cheesy to be honest but it all sealed up the way it should. The push in lines did too. Great product!

For the price, yep its a good product. Will take a bit of adjusting to get it set exactly to what spec you looking for. If you are shooting for under 10 psi, I would recommend getting another pressure gauge for the regulator. Reason being the pressure gauge provided come in 10 lb increments. That makes it hard to fine tune the lower pressures. Even with that still worth the buy. Its been operating in my 89 GMC 1500, 5.7ltr for almost a year and is rock steady.

Original review was not so positive but later found out I was in the wrong. I bought this because I wanted a regulator with a return capability with adjustability of 0 and up. What I got was an adjustable regulator that looked wonderful and had matching a connectors and hose with it. I didn’t pay attention to the EFI part of it and just threw it on my truck and it didn’t work. I already used the connectors so didn’t want to return it. Did some research and found out the spring inside is for fuel injected and is stiffer than one for a carburetor. So I took it apart and swapped springs and it works just fine. My fuel pump doesn’t create enough pressure to make it work so took it inside to the air compressor and hit it with 20 psi of air and it works. So if you order this make sure you have a powerful enough fuel pump for it to work.

This is a high quality regulator for a cheap price. I have used other brands before.. this one is the best value for my money.. would definitely recommend this one..

Not very impressed with this regulator, no markings to indicate flow direction, in/ out or return. The pictures on the add show a diagram that is labeled completely wrong, it labels the vacuum port as a return lol. Guage dose not work either, tested with another that worked.

In the description it says it's adjustable from 0 to 100 PSI I could not get it to go below 30 PSI my engine became a fountain of gasoline requiring me to remove all the plugs just to get the gas out of the cylinders

Fais sa job, même si on le voit pas sous le capot ! Les «tuner de char» veulent sa lecture.

Once connected it did exactly what it was intended to do. I needed to make a new bracket to secure it but that was the location I selected for installation.

Bonne qualité
