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.

A must have part
I swapped these out the same time I did the banjo bolts, an all I can say it wakes up the truck, it's night an day difference.

Get rid of that restriction
Very nice and well constructed. Installed easy and you can see and feel the difference from these compared to the OEM.

worked great
Bought a bunch of parts to fix a fuel leak, new bowl, lines, seals, high-flow fittings and while i was in there deleted my ebpv, new turbo base, and up pipes all from riff raff. Everything went right in first time without adjustments. Riff raff hasn't dissapointed me yet.

Very nice parts.
Removed stock check valves and installed these
They are machined right and I had zero leaks at start up. Great job RiffRaff! -
Great Upgrade
Did these along with banjos and FPx. WOW, what a difference! Only thing I was uncomfortable with is how far in these should be threaded. I felt like I might snap them but they haven't leaked which is great!

fuel upgrades
These fittings are a must when upgrading your fuel system. As others say im not sure how any fuel was even getting to the engine. Another awesome product from Riffraff. I also bought the FRX with this and WOW what a difference. Smoother idle, better throttle response, more power, brought my 7.3 with 280k miles back to life!!

Crazy Difference
These high flow CVD fittings are second to none. Once you pull your stock fittings out you'll immediately wonder how fuel even gets through there, then you take a look at the new fittings and you'll KNOW that your getting a good fuel flow. On top of that I noticed a significant difference in throttle response and MPG's.

Must have!
I’ve never, ever written a review before but these more than deserve it. I have purchased quite a few items from Riffraff in the past and have never been disappointed. These fittings should be a requirement when doing any fuel side upgrades. I’ve done a lot of mods on my 2000 F250 including some 1.5 injectors. These fittings made a huge, huge, huge difference in how the truck runs. I thought it was running great before i installed them, i was wrong. This fixed some issues I didn’t even realize I had. I just thought the injectors were a little more eradic and rough than stock. No sir. Can’t say enough.

Great mod
I was impressed on how it made my 7.3 more quite. Better MPG by one or two. I did this mod in conjunction with the banjo bolts. Make sure you get the Viton sleeves for the fuel lines.
