The 7.3L Power Stroke injectors sit in a brass sleeve that separates the injector, and fuel, from the engine's coolant. These brass sleeves weaken and fatigue from age and tend to split and fail. A common symptom is finding fuel in your cooling system. This happens because the fuel system typically operates at around 60-70 psi of pressure, whereas the coolant system operates at a much lower pressure so the fuel gets pumped into the coolant when the sleeve fails and cracks.    

We offer these custom made tools to simplify the changing of the sleeves. By design, the tools are shorter than an injector so you can change the sleeves with the heads on the motor and the motor still in the truck since there is no slide hammer required like with some other sleeve tools. These tools are Black Oxide and Hard Coat Anodized for long life. You can replace your sleeves as preventative maintenance now, or replace them later once you detect signs of failure.



Here are some basic instructions on how to use our tools:  Injector Cup Tool Instructions


Shipping: FREE SHIPPING includes regular ground shipping to the lower 48 US states. Orders overs $300 to new customers will ship with signature required.


Tool Rental:

Please note that we do NOT rent out our tools, EVER!! We strongly discourage renting a tool of this nature. Rented tools typically are abused and not cared for. We have sold many tools to customers that rented the cheaper tools only to have the tools break inside the injector sleeves!! That's hardly worth the few dollars in savings when you consider all the work and headaches of a sleeve R&R at that point. The tools will pay for themselves the first time you use them so don't take a chance on a used and abused tool set when you can purchase our new un-used tools at a very affordable cost.
