Aeromotive 13129 Regulator, EFI Bypass, Adjustable (2) -6 inlets, (1) -6 bypass

I used this regulator to maintain proper fuel pressure on my 7.3 Powerstroke -a 1997 model year F250. It is popular to upgrade the fuel systems on these trucks, and a good quality regulator is needed to maintain the required 65psi at the engine. I have used this regulator for approximately 20,000 miles now, and it has not needed any adjustment -after the initial setup. Although I did not find a specific manufacturer rating for compatibility with diesel fuel, I have had no issues or leaks. It maintains a constant 65psi at all times, and is able to return a significant volume of fuel; plenty more than my high-pressure fuel pump can supply. My regulator unit is mounted on the motor itself, where it is subjected to heat cycles, dust, and vibration, and has not leaked, loosened, or corroded. I will update my review in the event of a failure or any other problems, but I do not expect any.

Very good regulator, maintains pressure perfectly

Good quality product, exactly what I needed for my boosted Silverado. I was able to order some other pieces separately and assemble a nice fuel regulator setup to tap from my factory lines straight to my oem fuel rail.

If you are having doubt about buying this, don’t. Because you DO NOT cheap out on the fuel system. It’ll save you money in the long run, cheap fprs dont last, you don’t want fuel leaking or have false pressure readings. Just buy this you won’t regret it, also it will put your mind at ease as well.

After learning my lesson the hard way and buying 2 cheaper versions of fpr I spent the little extra and have had 0 issues with it.

Good quality

This is a great little FPR. It is well made and should last a long time. I am using it in a carb to fuel injection with turbo project I'm doing. I will add that the description is a little misleading here on amazon. The FPR does not have -6 AN fittings, it has -6 ORB fittings. There is a difference. You can't just screw AN fittings into it, you will need an ORB to AN adapter. The description says -6 AN at the beginning and -6 ORB towards the end. Make sure you get the right fittings to screw into this thing.
