Our warranty network expands throughout the United States, ensuring that our customers are able to be served in every state.

Worthington Industries warrants that its products will be free from defects in material and workmanship.  Worthington’s repair or replacement obligation, at our option, will be performed by our designated Certified Warranty Provider. The product and the labor associated are warranted for 12 months or 135,000 miles, whichever comes first. Our Type 3 CNG Cylinders are warranted against defects in material and workmanship for a period of ten years, regardless of mileage. Worthington’s Warranty is conditional upon its product being properly installed, maintained, and operated, and that its product has not been altered or misused, or damaged by others.
If repairs are necessary, we can help find a service provider that will be happy to assist you. If you're a service provider or heavy-duty truck dealer interested in joining our warranty network, we would love to hear from you.
Submit claims within the stated Warranty time period to Worthington Fuel Systems via the Warranty Claim Form. Photos of warranty issues and repairs must be submitted by email, fax, or mail. Fully filled out forms will then be processed for approval. Clearly label and return all defective parts within 15 days. All claims will be addressed within 48 hours of being received and every effort will be made to give urgent claims priority processing.
All repairs must be preauthorized with an assigned a claim number before completing any repairs. All claims must be signed by a certified shop’s manager (or an individual with signing authority) before being sent to Worthington Fuel Systems. Once the repair work is approved, the labor will be covered at an agreed upon rate, but Worthington Fuel Systems holds the final approval on the number of hours paid per each repair. Supplemental Warranty approval is subject to the warranty terms of the manufacturer’s component and the labor performed per their labor policy. Our warranty network expands throughout the United States, ensuring that our customers are able to be served in every state.
The statements above are for Worthington Fuel Systems’ Standard Warranty. Extended warranties lasting two, three, or four years are also available.
