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.

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.

The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.

The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.

All fluids must be drained.

If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.

Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.

Fuel injectors are crucial components of your vehicle's engine, responsible for delivering the precise amount of fuel needed for efficient combustion. However, various factors can contribute to fuel injector failure, leading to engine problems, poor performance, and even costly repairs. Understanding the common causes of fuel injector failure can help you take preventive measures and keep your engine running smoothly. Here are the main factors that can cause fuel injectors to fail.

Common Causes of Fuel Injector Failure:

  • Clogging and Carbon Buildup

    • Over time, carbon deposits, dirt, and fuel impurities can accumulate inside the fuel injectors, leading to clogs. This buildup restricts the flow of fuel, resulting in poor atomization, engine misfires, rough idling, and decreased fuel efficiency.

  • Low-Quality Fuel

    • Using low-quality or contaminated fuel can introduce harmful particles into the fuel system, accelerating wear on the injectors. Ethanol-blended fuels or fuels with excessive impurities can also cause corrosion or contribute to clogging.

  • Water Contamination

    •  If water finds its way into the fuel system, it can lead to rust and corrosion inside the fuel injectors. Even small amounts of water can cause significant damage over time, resulting in injector malfunction and reduced engine performance.

  • High Fuel Pressure

    •  Problems with the fuel pump or pressure regulator can result in excessively high fuel pressure, putting extra stress on the fuel injectors. This can cause leaks, increased wear, or even complete injector failure.

  • Electrical Issues

    • Since fuel injectors rely on electrical signals to function, issues with the wiring, connectors, or injector solenoids can prevent proper operation. Electrical problems can cause the injector to stay open or closed, leading to irregular fuel delivery and engine misfires.

  • Heat and Engine Vibration

    •  Continuous exposure to high temperatures and engine vibrations can weaken the seals and internal components of the fuel injectors. This may lead to leaks, reduced fuel spray quality, and performance issues over time.

  • Normal Wear and Tear

    •  Like any other engine component, fuel injectors are subject to wear and tear due to prolonged exposure to fuel pressure, heat, and use. High-mileage vehicles are more likely to experience injector problems as parts age and degrade.

  • Infrequent Fuel Filter Replacement

    •  The fuel filter helps to keep contaminants out of the fuel injectors. If the fuel filter is not replaced regularly, dirt and debris can make their way into the injectors, causing clogs and damage.

Fuel injector failure can result from a variety of factors, including clogging, poor fuel quality, high fuel pressure, and electrical issues. Regular maintenance, such as using high-quality fuel, replacing fuel filters on time, and keeping the fuel system clean, can help extend the lifespan of your fuel injectors. By understanding these common causes, you can take proactive steps to prevent injector problems and maintain your engine's optimal performance.

With regular maintenance and clean system components, it can last over 200,000 miles.

Symptoms may include misfires, sluggish throttle response, rough idle, or visible exhaust smoke.

Professional ultrasonic or bench cleaning is recommended to remove deposits without damaging internal parts.

Leaks can wash away lubrication, reduce compression, and impair combustion quality.
