This seems to be the preferred FPR. I am building out a parallel -6 fuel line kit & didn't have the big picture when I ordered this. I am now ordering a pair of -8 AN ORB to -6 Flare fittings from ScAmazon so I can still use this FPR as RSD doesn't seem to offer any.

Quality is amazing. I would not run any other FPR. I paired this with an IAG fuel pressure gauge could not be happier.

Aero makes some of the best, and cleanest regulators, I prefer the gen 2. You will be happy you bought it!

I always run these exact FPR on all my cars and bikes. Currently have 2 a1000 FPR. One feeding a static 65psi to my HPFP and the other to my Port injection @ 1:1. Also running 2 different fuel rails with separate pumps and returns. I want the project to finish already.... Picture is mocking up a location, clamp is gone now of course. :)
First off to anyone questioning in themselves on should they go with hot rod fuel hose for your build, let me try to help your decision. My first purchase from them went great. As in nice parts, fast shipping an over all great experience. So when the time came a few weeks later to get the rest of my fuel system done they came through perfect in every order. I even changed my mind on a part and they sent me a return shipping label within minutes of asking about said return. The parts are great quality and these guys are great to do business with...
I had a regular from on3 performance. It worked, but wouldn't hold enough pressure in the lines after shutoff. This would make the motor turn over more before startup. After installing this 13139 regulator, the car holds Pressure in the fuel lines making it easier to start. I know the pump primes before you turn the key during the starting process, but I'm telling you what works for my LS motor. The oring burbs are nice, but if you have an 8an return and don't want to change your lines, you will need an 6 ORB to -8an fitting. The old pump (china made) read 62lbs the 13139 reads 55 lbs at 14.8 fuel air ratio. I haven't figured that out yet. 62lbs on the aeromotive was 12.3 air to fuel ratio... too rich.
A very nice, quality product. Adjustment is very easy and makes setting a desired fuel pressure and breeze
Install was easy, options for -6 an fitting is great. Made putting together my fuel system very simple. It holds the exact pressure I set it to and it’s operation is very quiet. My custom bracket sucks but it does the job.
