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.

The Cummins QSX15 Fuel Injector, OEM 4928260RX, is a key component in maintaining optimal fuel efficiency in diesel engines. This injector set is designed specifically for the 2003-2010 models and plays an essential role in delivering precise amounts of fuel into the combustion chamber.

Key components of the Cummins QSX15 Fuel Injector include:

  • Injector Nozzle
    • Ensures a fine mist of fuel is sprayed into the combustion chamber.
  • Injector Body
    • Houses the internal components and provides a secure fit within the engine.
  • Control Valve
    • Regulates the fuel flow to achieve precise injection timing.
  • O-Rings and Seals
    • Prevent fuel leaks and maintain pressure integrity.
  • Electrical Connector
    • Links the injector to the engine’s control system, ensuring accurate fuel delivery.

Regular inspections and replacements of these injectors are crucial to avoid potential issues such as rough idling, reduced fuel efficiency, and even engine misfires. If you're noticing any of these symptoms, it may be time to replace the injectors to keep your engine running smoothly.

A failing fuel injector can cause significant problems for your engine if not addressed early. Recognizing the signs of a bad fuel injector can help you avoid costly repairs and keep your vehicle running smoothly.

Here are some of the most common indicators:

  • Rough idling
    • If your engine is idling unevenly or feels shaky, it could be due to a fuel injector that isn’t working correctly.
  • Poor fuel economy
    • A malfunctioning injector can lead to improper fuel delivery, resulting in increased fuel consumption.
  • Engine misfires
    • If fuel isn’t delivered consistently, the engine may misfire, causing poor operation and potential damage over time.
  • Starting problems
    • Hard starts can be another clue, especially if the fuel injector is not supplying fuel when needed.
  • Unusual smoke from the exhaust
    • Leaking injectors may cause excess fuel in the combustion chamber, producing thick, dark smoke.

If you’re noticing any of these signs, it may be time to inspect or replace your fuel injector. Addressing the issue promptly can prevent more serious engine problems and ensure your vehicle runs smoothly.

Injector functionality can be checked using diagnostic software, cylinder cut-out tests, or flow rate measurements.

 

Regular inspection is recommended during scheduled maintenance, especially if fuel system issues are suspected.

External buildup may be removed, but internal cleaning typically requires specialized equipment or professional service.

A single faulty injector can disrupt engine balance, causing misfires and performance drops across all cylinders.
