7.3L Diesel Fuel Rail Crossover™ (FRx) 99-03 Powerstroke

"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 by utilizing the FRx and creating a regulated return back to the tank.

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.

  3. Great kit 5 Star Review

    Posted by on Jan 16th 2016

    Installed return kit while doing some other work, well made, great price, and smoothed out my 7.3 like you wouldn't believe. My only regret is that I didn't do it 100000 miles ago.


  4. Less cackle, smoother idle 5 Star Review

    Posted by on Jan 14th 2016

    Couldn't be happier with this product, easy install, and a noticeable difference in the idle! A must have for any 7.3! Thanks Clay! Keep up the good work!


  5. So far, so good 5 Star Review

    Posted by on Jan 13th 2016

    Installed as part of turbo replacement. Also did CVD fittings. This has smoothed out my 7.3 so much it doesn't move while idling. Although I am wondering if there are any new noises that come with this upgrade.


  6. Truck seams to like it. 4 Star Review

    Posted by on Jan 12th 2016

    I replaced the turbo, turbo pedestal, up pipes. So access was there, the back connection was pretty easy, but the front one was a different story. Tight quarters to do the work also the hose to the front one was to short to wrap around the fuel bowl. So I had to go over the top of it. I hope it doesn't be a problem changing the fuel filter.


  7. Awesome piece 5 Star Review

    Posted by on Jan 4th 2016

    It works as advertising. Worth the money!!!


  8. Very happy 5 Star Review

    Posted by on Dec 29th 2015

    I was just about to do some elaborate regulated fuel return system mod and found this. I can't believe how much better my truck runs and how much quiter it is.Now for the hutch mod. I strongly recommend this for every later7.3. What Ford and international should of done from the get go!


  9. After 5 plus years, still great 5 Star Review

    Posted by on Nov 16th 2015

    Price, simplicity, function, it works. Great product Clay, keep up the good work.


  10. Must have for 7.3 5 Star Review

    Posted by on Nov 7th 2015

    Great product that is very easy to install. My injectors are happier now more than ever. Better acceleration and quieter at idle. On a side note if I were to install another one I would consider 9/32 square socket for the few extra dollars.
