I really think it is a great upgrade and a quality kit. The idea that the fuel isn't "dead-headed" in the fuel rail also helps. I think you will see a noticeable change in how the truck idles too!

Here is a post from the thread I started after installing the next gen FRx. Read the whole thread for more information.

I observed improved PERDEL numbers as well. However, in my case I installed the FRx and black CPS at the same time. Seems like they compliment each other because both of our pickups idle quite nicely.

That covering is pretty nice.

Since Trey is going for the stealth look, he might have to do something about the Riffraff brand on the FPR housing as well.

I realize that the FRx also provides better fuel pressure feedback info, so it's not only about the air in the lines.

I think you will still see some additional improvement. The Hutch Mod gets you back to a good running stock system as far as air contamination goes. Air in the fuel line isn't a problem until the pickup assembly breaks/cracks or the screens begin to get clogged. When the screens are clogged, the OEM fitting ahead of the fuel pump can allow air into the system due to a pressure drop at that point. At that point the engine starts to get a lot more noisy and performing hutch mod will make a big difference. In your case, the FRx will be a subtle change, but still worth the effort IMO...

You're right, it's not only about the air. Since #6 fires right before #8, and the fact they sit side-by-side, #8 doesn't always get it's fair share of fuel sitting at the end of the deadhead fuel rail. Open up that deadhead fuel rail with an FRx and #8 will be much happier with a better volume of fuel and might even last a bit longer because it will be better lubed. The fuel section of the injector is only lubed by the fuel, and any additves you may add to the fuel.

Ya, you should have some type of pre-pump filtration. If its only a clear bubble filter, its atleast something.

I installed a screw-on 10 micron filter just ahead of the tank - after I did the hutch mod. I like the fact that my fuel pump now only sees cleaner fuel, too. Ripping all that badly-engineered junk out of the fuel tank and replacing it with stainless lines brought joy to my heart.

JMHO but I really think this is 2nd best thing I've done to my truck only behind putting Bill's tunes on it
