Cummins Celect Injector Cummins Celect injectors are one of the most complex and advanced injectors in use today. The advanced technology in these injectors allows for increased power, lower emissions, and better engine responsiveness. Remanufacturing Cummins Celect injectors requires sophisticated equipment to recondition not found in many smaller fuel shops. Getting a CELECT injector to original performance specifications is 20 times more complicated than ordinary injectors. In other words, you can't just clean and rebox a CELECT injector and hope for the best. Mechanical injectors have one high pressure sealing joint while CELECT injectors have ten. In addition CELECT injectors have a much tougher cleanliness requirement and are much more difficult to assemble. Even if a rebuilder could assemble a CELECT injector, they would have no idea if it worked unless they obtained very specialized testing equipment. Plus there are critical hydraulic flow specifications that must be met in order for the engine to idle properly. If you are replacing one or two injectors, it makes sense to replace all six. Replacing all six Celect Injectors can increase overall engine performance and help to avoid potential problems, especially with higher-mileage injectors. Doing so will give you the assurance of knowing that your injectors are operating at peak efficiency to deliver maximum performance and fuel economy. Overhauls, tune-ups, and overhead set service are great times to replace your injectors.

***Our Core Policy Has Been Updated***

As of November 2021, the standard practice for The Diesel Store is to collect a refundable core charge at the time of purchase.

Pay Core Charge Upfront - Charge is Refundable

When you pay the core charge up front, you are eligible for a refund of the core charge if you send us the old core within 60 DAYS of purchase. At the time of purchase, you will be charged the full amount for the part and the core. As soon as an acceptable core is returned, you will receive a refund to the payment method used at checkout.

Definition of Core:

  • The core is the old unit, which was replaced by the new or rebuilt item.
  • Many replacement parts such as pumps, injectors, turbochargers and high-pressure oil pumps have a core charge that is associated with the part.
  • To receive full credit, all cores must be returned in rebuildable condition, must be like for like, and include all parts and pieces that were received on your replacement product.

Core Physical Condition:

  • No core credit will be issued for cores that have been in a fire, disassembled, or severely damaged or broken.
  • Partial core credit may be issued for cores that have been damaged, including those with a seized head and rotor, cracked housings, contamination (water, biodiesel, waste vegetable oil, etc.), or missing parts or pieces.

Core Return Process:

  1. Drain all fluids (oil, fuel, etc.) before the core is returned.
  2. Use all plastic plugs and caps received on the replacement item on the return core.
  3. Wrap in sturdy plastic bag to prevent leakage. Any wet packages may result in damaged or denied packages.
  4. Pack the core in the original box. Be sure to use any cardboard braces or internal cushioning provided.
  5. Include your purchase information together with the part, which includes either a printed email order confirmation, or a copy of the invoice included with the pump.
  6. Ship your core to us using the pre-paid return label included with your purchase (US customers). If you do not have that label, you may contact us for a replacement. Alternatively, you may ship to:

         The Diesel Store Core Returns
         1 Seidel Ct.
         Bolingbrook, IL 60490

  7. If for any reason you have questions or concerns on the status of your core, please e-mail the tracking number and invoice number to
