Warranty & Policies
- The core is the old part that is replaced by the part purchased from Diesel Injection Service.
- The charge for each injector core is listed on the corresponding product page.
- Customers may return cores at the time of purchase of the replacement part, to avoid paying a core charge. Otherwise, a core charge is required prior to fulfillment of your order.
- Cores must be returned intact and in rebuildable condition. Diesel Injection Service reserves the right, in its sole discretion, to return cores that are not intact or damaged and to deny credit for those cores.
- To prevent damage during shipping, cores must be returned in the original packaging, with protective caps in place.
- Credit will only be given for cores that are the same model as the replacement part purchased from Diesel Injection Service. Until Diesel Injection Service receives each returned core, in an acceptable condition, the core belongs to the customer and is the customer’s responsibility.
- Cores must be returned within 30 days of the original order date. Core credit will be discounted by 25% for cores returned after 30 days. Core credit will be discounted by 50% for cores returned after 60 days. Cores will be ineligible for credit after 90 days.
Cores must be returned to:
Diesel Injection Service

A shipping label is included for your convenience. Please use a new shipping box if necessary. If the shipping label is lost, return shipping costs then become the responsibility of the customer. Cores may be returned by UPS, USPS, FEDEX, or any other reliable means. The customer should decide whether insurance should be obtained on returned cores. A completed and signed core card must be returned with cores in order to expedite core refund. Diesel Injection Service will process core deposit refunds upon receipt and inspection.
Refunds will be issued to original source of payment.
Please allow up to 7 business days after cores are returned for credits to be posted to your account.
All orders placed before 5:00 pm PST Monday-Friday will be shipped within 1 business day.
