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 2 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.

  1. fuel upgrades 5 Star Review

    Posted by on Jan 25th 2018

    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!!

  2. Crazy Difference 5 Star Review

    Posted by on Dec 31st 2017

    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.

  3. Must have! 5 Star Review

    Posted by on Nov 16th 2017

    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.

  4. Great mod 5 Star Review

    Posted by on Oct 24th 2017

    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.

  5. Don't second guess it...buy it! 5 Star Review

    Posted by on Sep 14th 2017

    I installed these fittings when I did my turbo upgrades so I can't say it did anything for power and throttle response but I can definitely tell a difference on how smooth and quite the injectors were! Side by side with the riff raff fittings vs the stockers you can see a huge difference. Don't forget the 1/4 in sleeves. Like all riff raff products it was nothing but the best quality!

  6. It just makes sense 5 Star Review

    Posted by on Aug 13th 2017

    I was really impressed of the difference of opening inside these fittings over the original ones, everyone should do that on their 7.3l, for the price you get these and how easy it is to do, I think there is no reason not to

  7. The best there is 5 Star Review

    Posted by on Jul 4th 2017

    I love RiffRaff products and these are awesome as far as fuel flow and non restrictive compared to the factory ones, couldn't be more satisfied.

  8. Better than stock 5 Star Review

    Posted by on May 7th 2017

    These fittings were not to bad of an install. They flow a lot better than the stock ones. Make sure to buy new sleeves for these when installing them.

  9. Smoother Idle - Don't Forget O-Rings 4 Star Review

    Posted by on Apr 27th 2017

    Works as it should..Most of the reviews had additional upgrades included in the review. I chose to only replace the Fuel Lines and CVD fittings. Smoothes out idle and saw 2-3 psi gain in Fuel Pressure..Went from 53psi stock to 57-58 psi. Less drop in pressure during full throttle.

    When installing the driver side CVD, loosen the Alternator/Power Steering Assembly (4 bolts) to allow plenty of room to work. I'd also suggest removing the Fuel Bowl. (2 bolts) and plugs).

    Make sure you order the Parker Viton O-Rings for the fuel bowl lines... 1/4, 5/16, and 3/8...Order spares..cause you'll likely drop them when trying to install. for $2..it's worth it!
