SHIPPING POLICY

Tamerx Diesel Products ships via UPS Ground. Next day air shipping can be arranged for a reasonable price of anywhere from $50.00 - $100.00 depending on the weight of the product and your location. 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. If a replacement is determined to be necessary, we will then arrange for your replacement part to ship out ASAP and issue any necessary return shipping labels and/or documents.

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 essential components in your vehicle’s engine, responsible for delivering the precise amount of fuel needed for optimal combustion. However, like any mechanical part, fuel injectors can wear out or malfunction over time. Understanding what causes fuel injectors to go bad can help you take preventive measures and ensure your engine runs smoothly. In this blog, we’ll explore the common factors that lead to fuel injector failure.

Common Causes of Fuel Injector Failure

  • Contaminated Fuel
    • One of the leading causes of fuel injector failure is contaminated fuel. Dirt, water, and other impurities in the fuel can clog the injectors, leading to poor fuel delivery and, eventually, injector damage.
  • Wear and Tear
    • Over time, the constant opening and closing of the injector nozzle can cause it to wear out. High mileage, frequent short trips, and harsh driving conditions can accelerate this wear and tear, leading to injector failure.
  • Heat Damage
    • Fuel injectors are exposed to high temperatures within the engine bay. Prolonged exposure to excessive heat can cause the injector seals to deteriorate, leading to leaks and reduced performance.
  • Electrical Issues
    •  Fuel injectors rely on electrical signals to operate. Problems with the vehicle’s wiring, connectors, or control modules can cause the injectors to misfire or fail entirely. Electrical issues can also lead to inconsistent fuel delivery.
  • Fuel Quality
    • Using low-quality or incorrect fuel can lead to deposits forming within the injectors. These deposits can clog the injector nozzles, reducing their effectiveness and eventually causing failure.
  • Corrosion
    •  Moisture in the fuel system can cause rust and corrosion on the fuel injectors, particularly in vehicles that are not driven frequently. Corrosion can damage the injector’s internal components, leading to malfunction.
  • Improper Maintenance
    • Neglecting regular maintenance, such as replacing the fuel filter or using fuel system cleaners, can contribute to injector failure. Over time, debris and contaminants can accumulate, leading to clogged or damaged injectors.

Understanding the factors that cause fuel injectors to go bad is crucial for maintaining your vehicle’s performance and avoiding costly repairs. Regular maintenance, using high-quality fuel, and addressing any signs of injector issues early can help extend the life of your fuel injectors. If you suspect your injectors are failing, it’s important to have them inspected and serviced by a professional mechanic. For more information on vehicle maintenance and to find high-quality replacement parts, visit our website. Keeping your fuel injectors in good condition is key to ensuring your engine’s reliability and efficiency.

Signs include rough idling, excessive smoke, misfires, poor fuel economy, and power loss.

Routine inspections should be performed every 50,000 miles or during scheduled maintenance checks.

It restricts fuel delivery, causing engine hesitation, increased emissions, and rough operation.

Using high-quality fuel, replacing filters regularly, and performing injector cleaning reduce wear.
