High Flow Fuel CVD™ Fitting Set for Ford 7.3L 99-03
By removing the restrictive stock check valve fitting and replacing with our custom machined high flow check valve delete fitting you not only remove considerable turbulence, but also allow more than 3x more flow than stock. This allows you to feed up to Stage 1.5 injectors on your stock fuel system and not starve them for fuel while maximizing performance. We recommend changing the 7-004 fuel sleeves on the CVD fitting when you install.
- 7075 Black Anodized Aluminum
- 3x Higher Flow over stock
- Quick Easy Install
- Uses stock fuel lines for easy installation
- 100% Made In USA
Quantity of 1 = 2 Fitting. 2 fitting are required for new install, one per head.
*Note: These Check Valve Delete fittings aren't needed if you use the SS Braided Fuel Feed Lines as they already included adapters that service this purpose.

I installed the parts not areal easy install. but Iam 78 years old and have and have some, but it made a better running truck for me. stiffness in my hands

Excellent Part
These fit perfect and are just what the doc ordered for your truck. This is one thing most people overlook when doing fuel system mods and are a must have. They sure beat the heck out of drilling out the stock ones. Just remember to get new sleeves to go with these.

Crap Son
Noticeable difference to the ear and the foot.....enough said. Please include Viton sleeves or make sure anyone who orders these is notified of the need as one would assume (yes i know) that you have all you need to do install when you order.

Difference is awesome!!
I didn't realize how restricted the other fittings were until I got them off to replace them with these fittings. I installed these with the FRx and I can definitely tell the difference overall with the setup. My brother in law is going to be purchasing these after seeing the difference as well. Definitely recommended for the 7.3l.

Amazing product for the price!
Installed them and all I can say is wow! Can't beat em. Faster throttle response, starts alittle better, and has a crisp idle. I'd recommend it to all 7.3 owners.

Injectors very Happy!
The CVD fitting set does exactly what they are designed for, the injectors now have full fuel flow whereas the stock check valves was severely restricting needed fuel pressure to the injectors.
I installed the passenger rear fitting first,verified for any leak then fired up the engine,whoah! did the engine fire up fast! Installed the front CVD, did the leak check and fired it up, boy does the engine start fast now!
Coupled with the Riffraff FRX kit, the engine starts much faster,accelerates better,smoother running throughout the power band,50-80 degrees lower EGT,great idle rumble,reduced injector noise,feels like the 7.3L runs on all 8 cylinders now.

Throttle response!
I installed these while doing the FRx, and WOW what a difference they make! The throttle response is fantastic and were very easy to install.
I also added some Gasoila to the threads for good measure. -
Awesome Product
I just installed these on my 03 super duty.
All I can say is HOLY CRAP what a difference. A lot more fuel Sound better and Throttle response is like no other. -
Great product!
I recommend getting these through riffraff because they are awesome and all. You can also make your own regulated return like I did using these, special braided fuel lines and the FRX...here is the mod I came up with...enjoy and buy these from riffraff! My truck was much happier after I came up with my diy fuel system...
