We will do everything we can to make sure that you get the service you need. We understand how important it is to receive your order as quickly as possible.
In most cases Tamerx Diesel Products only needs one address, as long as your product is shipping to the same location as your billing information. In order to eliminate credit card fraud, your billing information must match the credit card you provide.

The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.

Tamerx Diesel Products provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.

Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".

If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue.

As is the case for the majority of the diesel products sold on Tamerx Diesel Products, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Tamerx Diesel Products will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.

What is a Core Charge?

A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.

30 Day Core Charge Hold

You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.

An aftertreatment hose is designed to withstand high temperatures and harsh operating conditions while carrying exhaust gases or pressure signals throughout the emissions system. Over time, constant exposure to heat, vibration, and environmental factors can cause the hose to deteriorate. Understanding the common causes of failure can help prevent leaks and maintain proper aftertreatment performance.

  • Prolonged exposure to high exhaust temperatures can cause the hose material to harden, crack, or weaken.
  • Constant engine vibration can loosen connections or create wear that leads to splits and leaks.
  • Physical damage from road debris or improper routing can puncture or abrade the hose.
  • Oil, fuel, or chemical contamination can degrade the hose material and reduce its durability.
  • Loose or damaged clamps may allow the hose to move excessively, increasing wear at connection points.
  • Age and normal wear can cause the hose to lose flexibility and develop cracks over time.
  • Delayed replacement of worn hoses can result in exhaust leaks, incorrect sensor readings, and emissions system fault codes.

Routine inspection of aftertreatment hoses and their mounting hardware helps identify signs of wear before a failure occurs. Replacing damaged hoses promptly helps maintain proper exhaust flow, supports accurate sensor operation, and keeps the emissions system functioning efficiently.

Yes, continuous vibration can cause the hose to rub against nearby components or loosen at connection points. Proper routing helps reduce unnecessary wear.
