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.

Engine misfires can be frustrating and may lead to more severe issues if not addressed promptly. One common culprit behind these misfires is faulty fuel injectors. Understanding how bad fuel injectors affect your engine is crucial for maintaining your vehicle's health.
What Are Fuel Injectors? Fuel injectors are responsible for delivering the right amount of fuel into the engine’s combustion chambers. They play a vital role in ensuring efficient engine operation and optimal fuel usage.
How Bad Fuel Injectors Cause Misfires When fuel injectors malfunction, the engine may not receive the proper fuel-air mixture, leading to misfires. This disruption can cause uneven engine durability and reduced drivability.
Signs of Faulty Fuel Injectors:
- Engine Stuttering or Hesitation
- Noticeable pauses during acceleration.
- Poor Fuel Economy
- Increased fuel consumption without any changes in driving habits.
- Rough Idling
- The engine may shake or vibrate when the vehicle is stationary.
- Difficulty Starting
- The engine may take longer to start or fail to start altogether.
- Unusual Noises
- Clicking or ticking sounds from the engine area.
Bad fuel injectors are a significant factor in causing engine misfires. Regular maintenance and timely inspections can help identify and resolve injector issues, ensuring your vehicle runs smoothly and efficiently. If you experience any of the above signs, consult a professional mechanic to prevent further engine complications.
Dirty injectors can cause stalling, hesitation, and sluggish throttle response.
Driving with a bad injector can cause engine damage over time and should be avoided.
Slight power loss, minor surging, and inconsistent idle may point to early injector degradation.
A failed injector can lead to a dead cylinder, misfire, and significant power reduction.
