For built-to-order items, we strive to have them shipped out within 24 to 48 hours of purchase, provided we are not awaiting receipt of your cores.

We gladly accept returns and process refunds for purchases made within a 30-day window. Kindly note, a 25% restocking fee will be applied to all returned items.

What's your Fuel Injector Warranty Policy? How does it work?

Warranty Claim Procedure
For warranty claims on any Holders Diesel fuel injector, please send the item to Holders Diesel Performance LLC for a thorough inspection. We require an inspection of the suspected faulty item before sending out a replacement injector. Upon inspection, the item may either be repaired or replaced, as determined by Holders Diesel Performance LLC.

Limitation of Liability
Our warranty covers only the fuel injectors supplied by Holders Diesel Performance LLC. We do not claim responsibility for any other parts. Please note that warranty claims are valid only for the original purchaser and are non-transferable.

Warranty Void Conditions
The warranty may be voided if there's evidence of:

  1. Tampering
  2. Fuel contamination
  3. Oil contamination
  4. Low fuel pressure
  5. Neglect (e.g., dropping injectors or improper installation)

Additional Charges

We do not cover any labor or shipping charges. Our warranty extends to the parts alone, not the installation. If an inspection reveals no issues and the parts pass all tests, a cleaning, testing, and re-sealing fee of $35.00 per fuel injector will be charged.

Warranty Terms
