Warranty Information

All of our products are covered by a minimum 6 month warranty period. 6.5L injection pumps and HD PMD’s have a 12 month / 50,000 mile warranty. Some products are warranted through their manufacturer. Not covered in the case of an injection pump warranty is damage due to water, gasoline, or other contaminants in the fuel which may cause hydraulic head seizure. Operating any injection pump on any fuel other than commercially available petroleum diesel including any homemade blends many result in jeopardizing the warranty if the damage is determined to have been caused by said alternate fuel. Please discuss this with us on an individual basis if you are thinking about an alternate fuel. All customers are highly advised to use Stanadyne performance formula diesel fuel additive!

HD PMD’s must be properly mounted and cooled to maintain their warranty. In the issue that a question arises, because of a custom “customer built” mounting, verifiable pictures of said mounting may be required. We will be fair, but reasonable precautions must be observed!

We cannot be held responsibe for loss of use, or any incedental or consequential damage to an engine or otherwise caused or purported to be caused by any product. All warranties cover parts only. Labor to replace a component is not covered. Also not covered is any damage caused through improper operation.

Before returning any component, please call or e-mail. All returns not due to an error on our part will be subject to a minimum 15% restocking fee. Only parts that were not installed and are in original undamaged packaging are eligable for return unless other arrangements are made. We desire happy repeat customers and will provide prompt personal attention to resolve any rare difficulty that might occur.
