Returns & Warranty


Your satisfaction is important to us. You have 30 days from original invoice to return any item purchased from the Diesel Injection Zone. To be eligible for a return, the product needs to be unused, in a “brand-new” condition. It must also be in the original packaging.

Once your return is received and inspected, we will send you an email to notify you that we have received your returned item, and, at our discretion, a restocking fee of up to 25% may be assessed. Shipping costs are non-refundable. Customer is responsible for shipping costs incurred to return products. Because of the product value, we recommend you to consider using a trackable shipping service or purchasing shipping insurance.

If your return item is approved, then your refund will be processed, and a credit will automatically be applied to your credit card or original method of payment, within a certain amount of days.
