Expedited shipping services are available for an additional cost. Standard shipping does not include any insurance and Dorch Engineering is not responsible for any shipper related damages. Shipping insurance can be quoted and charged to the order if desired.


All international shipping is via DHL Express unless otherwise noted. All applicable fees, duties, and taxes are the responsibility of the customer. Dorch Engineering. LLC is not responsible for any additional charges incurred for international shipments. It is up to the customer to be familiar with local fees and duties and to pay them for final delivery.

Cancellation/Refund Policy

All returns must be unopened, unused brand new products. Returns must be requested via info@dorchengineering.com and all return requests must be placed within 30 days of the original purchase. All returns are subject to a 10% restocking fee.

All returns require prior authorization via email before shipping, at which time you will receive the proper return address and instructions. All return shipping charges are the sole responsibility of the customer. Refunds will be processed after the items have been inspected and restocked.


All high-pressure fuel pump kits are under a lifetime warranty for the original purchaser of the kit. This warranty can NOT be transferred and is tracked by serial number. This warranty does not cover any labor or diagnostic charges incurred. It also does not cover shipping damages, misuse, or tampering. Warranty claims are all dealt with 100% by EMAIL ONLY. All return shipping charges are the sole responsibility of the customer. If the warranty claim is valid, Dorch Engineering will ship out the repaired and/or new replacement components free of charge.

Warranty Instructions

Email into info@dorchengineering if you have a warranty claim. You must include all applicable original order information, photos, and DATALOGS to get the process started. We do not accept warranty claims without following our diagnostics steps and providing our requested datalogs. DO NOT remove the Dorch Engineering HPFP before we have finished our remote diagnostics and have approved the warranty claim.

Once a warranty has been approved there are two options. The first option is to ship the defective item back to us for testing. If it is deemed defective, we will repair or replace the item for no charge and ship it back via ground shipping. If it tests good, then the customer will be billed for the return shipping of their choosing. Option two would be to send out a replacement item. This would require a deposit of the full kit price as a security deposit plus applicable shipping charge. Once the defective item is returned to us and inspected, we will process a refund for the entire amount of the security deposit.

Core Policy

For “Lift Kit” products, a core deposit is charged to ensure the return of the customer’s original vacuum pump core to Dorch Engineering. These cores must be returned within 60 days to receive a full refund of the deposit amount. All cores are subject to inspection and any physical damage will result in a denial of the refund. The refunds are processed after the inspections are complete and will typically be processed within 1 week of the arrival of the core.

Core return instructions can be found on the website or in your new Dorch Engineering Lift Kit package.
