Motorcraft 7.3L Powerstroke Injector Cup Kit 94-03 7.3L

These are OEM International injector cups and are priced as a kit of 8. We offer to rent you the injector cup puller/ installer as well with your purchase of the cups for a $499 deposit.  We charge $50 to rent the tool which will be deducted from your deposit, which also includes a return USPS shipping label that we can email you when finished. Although we have 32 rental kits in rotation they are not always available so check availability above for a shipping estimate. Rental tool orders are filled first come, first ship. 

Our Patented puller allows you to remove the cups without removing the heads or using a slide hammer.  Also, by using the tool to grab the cup, you are able to inspect each cup for damage once it has been removed. Other methods (typically a tap) are likely to damage the cup during the removal process and make shavings that end up in your cylinders. 

Our Patented install tool is really the break through since rather than trying to hammer on it in tight spaces and hope your cup is seated you simply use a socket and allow it to press the cup in.  This allows for a completely seated cup every time, no guessing, no hammering, even on the back cylinders or e-series vans. To ensure our install tool doesn't deform your new cup, like other competitors tools, we have machined it so that it engages both the full surface of the cup bottom as well as the top lip.  We have put an o-ring on it so you can strategically put your cup in the injector bore instead of dropping it in and hoping your sealant stays intact. In order to allow the cup to seat without turning in the head we have engineered the install tool with a ball bearing so it remains stationary while you turn in the press.

We also have retaining compound and injector orings available for purchase that is used by Ford and International when reinstalling the cups.

Please note that if the tool is not received back by 30 days from customer receipt then there will be a $25 late charge.  If tool is not returned in 40 days you will loose your deposit.


Kit Includes - 8 Injector Cups and optional rental of the tool.

  1. Precise Tool! 5 Star Review

    Posted by on Mar 16th 2018

    Was a precision and easy tool to use. My buddy who is a Ford tech helped be and couldn't believe how much better this tool is than his OTC slide hammer tap and punch. Litterly saved me thousands on this repair. You guys rock!

  2. OEM Quality can't go wrong 5 Star Review

    Posted by on Mar 13th 2018

    Best price on cups and Clays tool for extraction and pressing in is the best on the market, very precision tool. This procedure couldn't have went any smoother with his rental tool. It is extremely easy to use both the extraction tool and the tool for pressing in cups.
    I did learn something from Loctite Tech support, as I wanted to know what temperature does the Loctite 620 retaining compound work at. They told me 60 degrees Fahrenheit and above, and suggested using Loctite SF7649 Primer for below 60 degrees. Since the temps here in AZ have been below 60 for a high the past couple weeks I went with this. It came in a 4.5 oz spray can, so I used a small Artist's brush and sprayed it on the brush liberally and applied it too the injector bore where the retaining compound will meet with it. The Tech guy at Loctite said it is for speeding the cure of retaining compound as well as temps below 60 degrees. Also, you will want to purchase the Injector bore brush set to clean the bores, very important. Thanks Clay, as always you have all my diesel needs.

  3. Saved me $$ 5 Star Review

    Posted by on Feb 6th 2018

    What an amazing company! Received my OEM cups and sent back the discolored dorman I got from auto zone. I also rented the tool, that thing is amazing! I almost bought a tool from eBay but after doing this job I can't imagine using another tool. It was so precise and well engineered. I am so glad I found you guys and didn't let the local shop charge me almost $3000 for this job. $50 rental fee, cups, and rings and I was done. 5 stars!

  4. Have no fear, riffraff is here 5 Star Review

    Tool made the job easy, dont forget to order the sealant like I did...

  5. Do not do the injector cups without this tool 5 Star Review

    Posted by on Dec 26th 2017

    The tool made it so simple to remove and reinstall the injector cups in my 99.5 7.3. Do yourself a favor and wait for the tool.

  6. Easy as could be 5 Star Review

    Posted by on Nov 1st 2017

    Product arrived in a couple of days, tools were in great shape, completed the job in a few hours and sent back the loaner tool.. thanks! I'm sure doing it my self saved at least a $1000.00

  7. Excellent set 5 Star Review

    Posted by on Oct 29th 2017

    This is my first time doing this so I was really nervous about even attempting this job, but the $3000 - $5000 dollar quote to do this job forced me to take a chance. Not sure about the Rosewood set as far as pounding the cups in especially the back four, but this set of tools made the job a breeze. Hardest part for me was cleaning the back four cylinders, so I bought a endoscope from Amazon which hooks to my phone, still a pain but was a life saver. Thanks to Riff Raff diesel and all the forums for the help!

  8. Quality tool and easy removal 5 Star Review

    Posted by on Oct 20th 2017

    Couldn’t have done this without the riffraff removal tool. I have used the other slide hammer and removal tool, nothing compares. If your doing the cups on your 7.3 the only way to go is riffraff removal tool.

  9. just what I needed! 5 Star Review

    Posted by on Oct 16th 2017

    Good price, great product and fast shipping!

  10. Good stuff 5 Star Review

    Posted by on Sep 27th 2017

    Received these cups well packaged. They fit perfect and were smooth enough to not cut the o-rings on the injectors when installing. I would buy again, but I hope I don't have to!
