Product Description

"The Prescription For Your Fuel System Needs®"

We are now shipping our 2nd Generation FRx System that utilizes Eaton Aeroquip® 304 Stainless Steel Braided lines. 

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.

Protective covers are also pre-installed to prevent chaffing of engine components from the SS braided line. These covers are also great if you want to keep the system looking OE and not draw attention to it once installed.

- FRx System
- 3 Springs for adjusting Fuel Pressure

  3. Best thing I've done for my truck. 5 Star Review

    Install is straight forward and very easy. I only had to loosen the fuel bowl for installation. It is hard to tell what this product by itself did for the engine noise and performance because I installed the HPx at the same time. The FRx and HPx together made a very noticeable reduction in engine noise and vibration. Idle is nice and smooth and low speed acceleration is more responsive. In my opinion, the piece of mind that this provides is well worth the price.

  6. Best product. 5 Star Review

    Posted by on Feb 26th 2015

    I installed it on my 7.3 superduty. It was okay to install found it was easy to remove the ac compressor and move it over to get the plug easier. I love the throttle response now. The only thing i wish is the the block and where the lines that come out were angle down move so it looked move factory.


  7. good quality 4 Star Review

    Posted by on Feb 25th 2015

    installed on my 2000 f250, it was tougher than I expected but everything works like they said it would


  8. Great product, tight fit 4 Star Review

    Posted by on Feb 23rd 2015

    Installed on an e350 prior to motor going back in. Tight fit.


  9. Great design, well built & complete! 4 Star Review

    Posted by on Feb 12th 2015

    Installed the Fuel Rail Crossover™ (FRx) on my 01 F250 Superduty to balance fuel return between the injectors and to reduce dead heading plus to quiet down some injector clatter. Didn't notice much difference initially in sound but when i was cruising at freeway speeds I could feel the difference in response and a smoother, quieter power delivery.
    Installation was a bit cramped, plan your hose routing especially for the left bank. I removed the ac compressor with out disconnecting hoses on the right side, plenty of room with the compressor moved slightly over.


  10. Well built and easy install 5 Star Review

    Posted by on Feb 11th 2015

    This parts made a HUGE difference in the way my rig runs, starts, and accelerates!

    Like instructions say, beware not loose the spring, also the nut on the of fuel Lin coming into the fuel bowl can slip down the tube and end up out of reach!! I spent 30 minutes trying to get it back up the line. Wrap black tape in the line behind it so it doesn't go down the fuel line
