RiffRaff FRX line??
Do any of you guys have one installed?? is it a beneficial upgrade?? did you notice a difference after installation?? How hard was the install??
Let me add I have Clay's HPX line installed and it was an easy install for me, fit well, and I feel confident its doing what it was designed to do, VERY GOOD quality piece.

They are return lines. It does just what Riff-Raff says it will do, removes the dead-end fuel flow. I'm happy with it on mine, it's a nice piece.

I will throw a guarantee that if you don't think it helps send it back for a full refund

I had the Gen I and traded up for the Gen II. I think it's a great product for a reasonable price and works as described to boot.

It did quiet down mine and believe it works as advertised, also u can adjust fuel pressure with the 3 different springs included with it. Its kind of a pain to get to the pass side fuel rail plug. If u have a 5/16 spline wrench or a socket that will work the best. I tried everything else and couldnt get it until I found a spline wrench. Also getting the spring in there correctly is kind of a pain but I love the thing. I have one more to install on my other truck.

That is for sure, total class act with excellent quality at a very reasonable price. I will be picking this mod up sooner than later.

I don't see how excess fuel & air return back to the tank unless there is a port I can't see on the machined block. To me it looks like it returns back to the feed side of the bowl not the tank. Can someone correct me???
