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
- 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. 

1999-2003 7.3L Powerstroke *VLV-4 Fuel Sleeves are recommended for installation

    CCv fitting

    Posted by Dustin on Jul 6th 2020

    Installed these and they are way better then the factory fittings. Then when I changed injectors I bought the stainless steel fuel lines To bad the CCV fittings don’t fit with the stainless steel fuel lines that RiffRaff sells Ended up not using them after new lines came in .

    CVD fittings

    Way more flow then the stock fittings and good quality. Be careful when taking the stock fittings out, the one on the rear passenger side broke off in the head and was difficult to extract out. But overall I am happy with these thanks riffraff

    Better flow never hurt

    Not particularly easy to install but you wont starve your injectors.

    First negative thing i've had to say about riffraff products. These fittings are fairly cheap and thin not too mention very light duty. Installing these fittings was a pain. Not only did mine not fit but as I threaded it in, it was stripping a piece of metal off the fitting. No it was not cross threaded. As I tightened it down, the fitting snapped causing over 5hrs of headache. Everyone is way better off using the oem fittings and drilling them out. Other than that I love riffraft products, except this one.

    Another need to do install

    Posted by michael manuel on Apr 2nd 2020

    Take it from me but as minimal as it looks it’s much needed. Since it’s so low at cost and it’s much needed if the FRX upgrade is in your sights you might as well do the cvd fittings also since you’ll be working in the area. You won’t be disappointed and you trucks gonna live you more. You’ll u defat and when you’ll hear it idle after the install. Thanks clay and everyone at RiffRaff for the collective efforts to deliver such awesome products and always in timely manner.

    High Flow Fuel CVD Fitting Set

    Another NO BRAINER investment. Remove the restrictive OEM and replace with this. Larger opening and no check valve surely means better flow of fuel.

    I bought these for my fathers 99 and couldn’t believe the size difference. The stock one are a huge restriction. I bought them for my 02. Don’t forget the o-rings.

    Money and time we’ll spent!

    Posted by R.A Deyang on Jun 24th 2019

    I recently installed these along with the banjo bolts and it shocking the difference that it made. Once air was purged, the first thing I noticed was throttle response, dramatically better and smoother. My truck effortlessly accelerated and did everything better. The next thing I noticed was how much quieter it got. My noisy 160/Stock injectors has actually quieted down quite a bit. I didn’t have to turn the truck off to order anything at a drive though and idling it sounded like it had pilot injection enabled. I’ve been working on 7.3 trucks since 2001 so I know how they sound and respond Stock and modified. After installing the complete Riffraff Fuel system (Frx, Banjo Bolts, and CVD fittings) my truck is noticeably quieter at idle and even at speed. Money spent on this is money well spent, especially if you plan on larger than Stock injectors.

    Quality Product

    These fitting are worth the time and investment. Stock fittings barely allowed fuel to flow through. I'm glad I made the right choice.
