    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, by clicking to agree, 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.

    What is "Core Return Shipping Cost"?

    This product is remanufactured and requires that your original part being removed (core) to be returned. The return shipping charge of your core is not included in the purchase price of the item, but we offer you a flat rate charge that includes a core return shipping label as a convenience. If you would like a core return label included with your purchase, please select this option.

If you're looking at this product page, it probably means you're in the same boat as many, and have a dead or dying VP44 injection pump. The factory injection pump that came standard on the 98.5-02 Dodge Cummins trucks could best be described as a Band-Aid, or temporary fix, while Bosch was in the process of producing the common rail injection pumps that would be featured on the 2003 and newer trucks. While the VP44 is not necessarily a bad pump, they do have the highest failure rate compared to any of the other pumps, and most of the issues stem from inadequate lift pump pressure.

We can do these pumps in a package deal with FASS lift pumps, BD lift pumps, Pure Flow lift pumps, BD Stealth Covers, BD Low Pressure Warning Lights, gauges, etc. We will help you decide what is best for you to help protect your new VP44 from future damage. These pumps are re-manufactured using all factory Bosch replacement parts and calibrated on a Bosch test stand. The pumps are re-manufactured to strict Bosch standards with the most recently upgraded parts and the pump is calibrated to current specs. Further, these pumps feature new Bosch electronics and housing to ensure you're getting the highest quality pump on the market. Yes, you will find lesser expensive units, but they will typically feature remanufactured electronics that have shown a high failure rate. you REALLY want to have to do this job twice (or more)?

  • If you have been running biodiesel of B20 or above this could jeopardize the core being accepted. If you have been running vegetable oil, heating oil, kerosene, transmission fluid or anything similar your core will be considered non-rebuildable and your core charge will not be refunded. The core MUST be rebuildable to be accepted!

WARRANTY - These pumps carry a one year warranty. Splicing wires for performance adding chips voids warranty. Please consider purchasing the BD Stealth cover if you intend to use a chip. Running anything besides diesel or biodiesel blends of B20 or above can potentially void your warranty. It is recommended that a competent repair shop install your new pump. We will not warranty pumps damaged by improper install. These pumps do not ship with installation instructions.
