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.

Quality Cups, Awesome Tool!
The stainless steel cups appeared to be well made. The material seemed to be thicker than the original cups. They seated and sealed perfectly. The Riff Raff injector cup tool is awesome. It made the part of the job I dreaded most (cup r&r) the easiest most painless part of the entire job. It only took about 20 minutes a cup for r&r . Now cleaning each bore properly was another story. Overall very happy with cups and tool!

Best
I bought 2 sets of factory brass injector cups for 2-7.3L stock engines. Both only made it around 60,000 miles before some cracked again. I know 2 people that installed these well built stainless cups. They both are daily drivers and have a over 130,000 mile of hard abuse with out a single problem. One guy pulls a 3 car hauler. The other guy is pushing well over 500hp. These injector cups look and feel well built. Not all weak made like the brass ones. Don’t understand why Ford and international came up with such a cheap design flaw. When the engines are build so well. Every 7.3.L owner should spend the extra money. Put a set of these bulletproof injector cups. Save the hassle of kelp replacing the crappy made brass ones. People...Do it once, Do it right. Thank you Riffraff diesel making a solid product and solving the problem.

Arrived on time, well packaged, and very high quality machining. Impressed with this product all the way around. Install was a breeze with the rental tool, much easier than seen on YouTube beating cups in with a hammer.

Problem solved for good
Rented the tool and purchased these cups due to fuel in my coolant. Precision looking cups, very well packaged and tool made the job easy to accomplish even in my garage. Running these for about a year and no issues at all, still sealed and would recommend them. Just don't forget to rent the tool as it couldn't be an easier way to install them.
