I was using a homemade tool to do injector cups and it ended up damaging the cup more than actually working. I was stuck since the truck is my daily driver and I have 2 little ones I have to take places. I bought this and had it overnighted. Oh man was it easy to use! The project flew once I got this tool. Highly recommend getting one if you plan on having a 7.3 for a while.

Very well crafted tool set quality only hurts once! Once you get a feel for the tool it goes very quickly the cups remove and replace easily.

I liked being able to crank them down to a measured torque to ensure uniform and correctly installed cups the first time every time. It gave me the confidence to tackle the job myself and know that I had it done right the first time.

Heck even with the purchase of this tool set it was still cheaper for me to do it myself even if I only use the tool this one time it has paid for itself.

Not much I can say that the others have already said!

A must have for doing injector cups on a 7.3 ~ works better than all the rest. If your looking at this tool buy it. I still recommend you put a penny down in the old cup before pulling it ~ just for good measure.

I have used other "rental" pullers and installers in the past, but when a good friends 7.3 leaked, I researched and bought this one.
What a great purchase! This tool rocks!, precision made, looks like some almost overkill quality and machining my tool and die dad would have made, works so good in vehicle, don't purchase other crap, get this thing, even the packaging is quality. Makes it too easy.

Removed and installed cups with no problem. Took a couple cups to get the hang of removing it from tool. I put tool in vise and removed with channel locks. Would recommend it to anyone. Thanks for the great product.

Set is top notch. I appreciate all the detail that went into this product. The tool dedicated hard case is so official. This tool pays for itself in the first use, even if you use it once. It is important to support shops that create products in USA. Thank You.

very easy to use in removing and installing cups easier than trying to pry cups out and hammer cups back in would like to see extra orings and bolts like what hold the injector in instead of the allen head type

The design of this tool is perfect I have been a diesel tech for 25 years and this tool has the tech in mind.... the tool works like a dream. It does the job just like it says it will!! The guys who designed it knew what us{the tech} wanted in a tool. The big car companies need to follow suit here and start asking techs about tool design. You guys nailed this one dead on!!!!!!!!!!!!!!! thank you so much!!!!!!

I recently purchased this tool for installing the cups in my two 2001 f250 pickups. Not only is this tool simple in design it is effective and very easy to use. It beats the heck out of pulling the cab or heads to do the injector cup installation. The only thing in would have as a recommendation is that riff Raff diesel would come out with a wire brush set specifically for cleaning the cup mounting surfaces. Outside of that I am thoroughly impressed with both the tool set and with riff Raff diesel's customer service. Special thanks to clay, he was an excellent example of good customer service and very helpful. I look forward to doing business with riff Raff diesel in the future.
