I really cant stress how nice this tool set is, from the custom case, to the packaging, to the actual tooling. Using them made the job easy, and I really cant see how you would ever get it done by trying the hammer in tools. Highly recommend this engineered master tool set.

One of the best engineered piece of tooling I ever used. Very well designed. This tooling is highly recommended for removal and installation of the injector cups.

Since this is my first 7.3 and first time doing Injectors & Cups, I watched many Youtubes on how others installed their cups before I decided to buy this tool - And even then I dreaded the job.

WOW! - This is the only tool to get and use for this project. I feel sorry for those that have bought others (Esp the hammer in tools). It works so easy that the cleaning of the bores is the hard part.

Was way easy to remove the old cups. Spent more time taking old cups off tool than removing them.

As a former diesel mechanic, which has been several years since I work in the field, I found this tool to be extremely beneficial to the maintenance I am performing.
Even though there are no instructions, this is so easy to use I can’t believe somebody didn’t develop it earlier. It beats the heck out of every to hammer your injectors into the hole, especially the hard to get to rear injectors.

I am extremely pleased with this tool.

Because I don’t work in the industry, the price was a bit difficult to swallow, however, I’d rather do the job safely and efficiently as possible. So, i decided to bite the bullet and purchase it. Thank you for taking the time to develop this tool. (Maybe I could rent this thing out and recoup some of my money, lol, just kidding!

Thanks again,
Steve

I have owned the rosewood diesel tool for many years and thought that would be good enough to install RR stainless injector cups; Not so much!!! I installed all 8 stainless cups with that tool and I got oil in the coolant. I read the reviews on this tool and none of them including this one does this tool justice. I am a Master technician and have been for 30 years and One many snap on tools, this tool is snap on met starret, I don’t have the words to describe the Quality and attention to detail that this tool exudes, it is absolutely perfect for what it was design to do. If you were on the fence about this tool buy it it is worth every penny of $342!!!!!!

Just wow is all I can say, this puller and installer and it so easy to replace the cups in my ol girl. 330k miles it was time, new full force injectors and it's like a new truck. Great tools clay thanks!

tool works perfect. fits in tight spots had no trouble changing cup on my ford excursion.

I am a professional mechanic and also gunsmith. I own many specialty tools for both trades. When it comes to doing certain jobs it is best to buy the correct tool for the job. I searched the many tools available for the 7.3 cup job and decided to spent the more money and buy the special Riffraff tool kit. I was totally amazed of the ease of doing this job in place with the puller and installer. No hammer needed as the confined space the installer worked like a gem. The new style thread cutter did not leave shavings in the old cups. I did the tape and penny trick in each one just in case but really not needed. I actually enjoyed doing this job because how the tools made the job so easy. The tools are well manufactured and worth their weight in gold. 5 stars in my book.
