What do you guys think about this product. I have yet to see any discussions on this and thought it could use one for the people on a budget that want to improve their trucks without having to spend the money for a full RR or a fuel bowl delete.
I'll admit, I bought the original version when I had my 01 7.3 and I believe it made a bit of a difference in idle and noise. I would like to think it has to be better than stock but how much better is a full RR compared to this?
DFA used to have a setup similar to this but IIRC they are no longer in business and this is the only thing out there that I know of like this.
We are now shipping our 2nd Generation FRx System that utilizes Parker® 304 Stainless Steel Braided lines. You also have the option up upgrading to the 2nd Generation FRx for only $100. Just click the option above, we will ship you the new 2nd Gen FRx and when you return the original we refund the difference.
The FRx was made to solve the 'deadhead' fuel rail issue on the 99-03 Powerstroke engine by connecting the two heads and allowing a metered return you allow the air another return path, rather than forcing it through your injectors. This product was designed to eliminate the need to cut your return line and use compression fittings, so that it is a true bolt on system. We have also machined the FRx block to provide from stock to 72 psi of fuel pressure depending on which spring you choose to install it with. By using our kit and eliminating the air in the fuel system you will experience smoother, quieter idle, less cackle, and better throttle response among other things. You will also be increasing your injector life as well.
You can also select the option for protective covers to be installed to prevent chaffing of engine components but don't want to provide your own. These covers are also great if you want to keep the system looking OE and not draw attention to it once installed. We are making this an option, and not stantard, because some people would rather have the SS braided look in their engine bay.
