About guzzle's Diesel O-rings and Repair parts

Established in 2007, DieselOrings originally started as a simple help site that can still be found at to assist new Powerstroke owners with maintenance and modification tips. We quickly outgrew our ability to supply the basic Viton o-rings with e-mail orders in 2005 and 2006 since the additives in the new LSD and ULSD were beginning to show their devastating effects on the factory Nitrile (Buna-N) o-rings in both the fuel and oil systems of the 7.3L engine. In 2007, was born.

Located in Colorado, about 50 miles northeast of Denver, we pride ourselves in fast delivery of these small parts and kits using USPS and UPS delivery. With Same-day shipping, most customers will see their repair parts within 2 to 3 days of their order. From the very beginning, our mission has been to quickly supply the necessary parts to repair the multitude of leaks that can develop on the 7.3 at the lowest possible cost.

As we have grown, so has the number and types of parts that we offer. We continue to strive to develop new kits and a greater selection of  parts to offer to our customers.

If you need help in determining what your problem is with your 7.3L Powerstroke, call me and I'll try to help you pin it down, after all, we started as and continue to be a help site. 970-368-4455, if you get the voicemail, leave a message and I'll call back.

Thank you for your tremendous support,


 Bob - 'guzzle'
