    Terms & Conditions

    We at Diesel Power Products offer a deferred core program in which we allow you to defer the typical upfront core charge when purchasing via credit card payment. All cores, whether the core charge was deferred or not, must be returned within 21 days from delivery date of product requiring core charge. Failure to do so can result in forfeiture of the entire core charge return. In the event you originally deferred the core charge, you authorize Diesel Power Products to charge you for the core charge.

    All cores must be returned to the original warehouse that original shipment was sent from. If a return label is provided in the original shipment, use this tag. If one is not included, contact us immediately, and we can provide you with the correct address of where the core(s) must be returned to, as well as an RMA (Return Merchandise Authorization) number. DO NOT rely on the return address on the original label as a source for where to ship to.

    If cores are shipped to the incorrect warehouse, your core money will be returned less the shipping cost for us to send the core(s) to the correct warehouse, or if you deferred the core you may be charged for the shipping amount.

    Cores that have been disassembled and/or have missing and/or damaged major components will not receive full core credit. Returned cores must be on a "like-for-like" basis, meaning that the returned core has the exact same fitment as the remanufactured component that was purchased. In the event that the core is not "like-for-like," your core may not be eligible for return / credit.

    Diesel Power Products has the right to alter this policy (i.e. extend the terms) for any reason. If you have an outstanding circumstance, contact us.

    What is a "Core Charge"?

    In order to understand what a core charge is, you must first understand what a core is. In the automotive industry, most products are manufactured from brand new materials. However, numerous products are also remanufactured, meaning that the manufacturer of the product takes a used product, typically removed from a vehicle, disassembles, and replaces all worn components of the master product. A great example of this is in regards to automatic transmissions in which the manufacturer takes an existing transmission, replaces all of the inner working components, such as the torque converter, valve body, etc. and merely reuses the case.

    Because aftermarket manufacturers require a steady stream of incoming cores to build, they charge a deposit on the core, known as a core charge, that is refunded upon receipt. In some cases, the core is not reusable, such as in the event of a cracked case, at which point the core deposit would not be credited as the core component is not reusable.

    If you plan on returning your core you have two options.

    OPTION 1:
    You can accept it, which means you will be charged for the part AND the core at time of purchase. You still have the option to send it back, and if you do, the core will be refunded back on the card used, presuming the core meets core criteria and the core is returned within 21 business days from originally receiving your order. If you have outstanding circumstances that would not allow the return to occur within 21 days, please contact us.

    OPTION 2 You can defer the core charge. If you defer it, you will not be charged a core at time of purchase. You will have 21 business days from the day you receive it to send it back. As long as the core is received within the 21 business days, you will not be charged. If 21 business days goes by and you do not send it back, the card on file will be charged the core amount. You still may send it back, and once received, we will issue the core amount as in store credit, pending any limitations as set forth by the manufacturer.Core deferral is limited to payment by credit card only.

These are genuine Bosch remanufactured CP3 injection pumps for 03-07 5.9L Common Rail Dodges. When we say Bosch remanufactured, we mean actually remanufactured by Bosch, not built by Bosch, remanufactured by someone else.

Bosch Advantage: The advantage to being rebuilt by Bosch is they have the ability to completely "gut" these pumps from input to output to ensure they are as close to new as possible. There's no reason to pay enormous costs at the dealer, these are the same pumps that they're getting.

CORE CHARGE: An upfront core charge is required. Once your core is received and processed, we will promptly issue credit back to you. Please contact us if you have any questions.

Very Satisfied
Very satisfied with this product and the quick shipping provided. I went with this one due to it being rebuilt by Bosch and wanting to keep it 'stock'. The slightly higher cost over the others was worth the piece of mind and I still feel the price was fair. Install when smoothly and she started up almost immediately after priming.

Good choice on a high quality Bosch Reman CP3. There are cheaper reman options out there, but none compare in quality to this option from Bosch. -Ben
Service was excellent. Delivery right on time...
Service was excellent. Delivery right on time and the price was 65% cheaper than the price the Dodge Dealer wanted to charge me for this injection pump! Also very much appreciated the call after I had received the pump to see if all was well. Very pleased.

Solid reman product
Bought this to replace the pump on my 2005 5.9L that had problems with the case bolts loosening causing leaking and eventual failure. My truck is stock and I plan to keep it that way so no need for modified pump. Looked at several remanufactured options and chose the Bosch based on the argument that a pump remanufactured by the original manufacturer would be of superior quality. It installed easily and fired right up. No leaks and performance is good. Only a few thousand miles on it but very happy with this purchase.
