With your purchase of the cups, we offer you the option to rent the injector cup puller/installer for $75. The rental fee will be taken from the $499 rental tool deposit paid at checkout, with the remaining deposit refunded upon our receipt of the rental tool in good condition. Simply email us within 30 days when you finish with the tool and we will send you a pre-paid USPS shipping label to return the tool.* 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 can 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 create shavings that end up in your cylinders. Our Patented install tool is really the breakthrough; rather than hammering on your new cups in tight spaces and hoping they are seated, simply use a socket and allow the tool to press the cup in. The tool allows for a completely seated cup every time; no guessing and no hammering, even on the back cylinders or e-series vans. To ensure our install tool doesn't deform your new cup as our competitors tools do, it is machined to engage both the full surface of the cup bottom and the top lip. The tool also features an o-ring as a keeper to allow strategic placement of the cup in the injector bore instead of dropping it in and risking displacement of your sealant. In order to allow the cup to seat without turning in the head, the install tool is engineered to include a ball bearing to prevent cup rotation while being pressed in. We also have available for purchase the retaining compound and injector o-rings used by Ford and International when reinstalling the cups. |
*Please note that if the tool is not received back within 30 days from customer receipt, then a $25 late charge will be withheld from you deposit. If tool is not received back within 60 days, you will lose your entire deposit. |
Set Includes - 8 SS Injector Cups and optional rental of the tool.

Stainless Steel Injector Cups
Really can not recommend these strongly enough. Way better quality than stock brass cups. Do yourself a favor and just do it right the first time and have your truck reliable for another 30 years.

Great quality
I forgot to select the sealant, so wound up using Loctite 620 and the SF 7649 primer (needed for stainless steel). They were a breeze to install and the truck is running incredible now with the cups and Full Force reman injectors.
