***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.
