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 QSK Fuel Injector (OEM 4964172) plays a critical role in delivering precise amounts of fuel to the engine, ensuring efficient combustion and optimal performance. For engines running from 2008 to 2021, maintaining the fuel injectors is key to keeping your engine functioning properly and avoiding costly repairs.

Why the Fuel Injector is Vital

The fuel injector's main role is to deliver fuel into the engine's combustion chamber in a precise and controlled manner. For the Cummins QSK engine, a high-performance fuel injector like OEM 4964172 ensures the engine operates efficiently while keeping emissions low and fuel economy high.

Key Functions of the Cummins QSK Fuel Injector

  • Reduces Emissions
    •  By delivering the correct amount of fuel, the injector helps minimize exhaust emissions.
  • Improves Fuel Economy
    • Proper fuel atomization leads to better fuel efficiency, saving on fuel costs over time.
  • Prevents Engine Wear
    • A well-maintained fuel injector prevents engine knock and unnecessary stress on engine components.

Tips for Maintenance

  • Regular Inspection
    • Check injectors for signs of wear, such as reduced fuel economy, hard starting, or rough idling.
  • Timely Replacement
    •  Replace the fuel injector with the Cummins OEM 4964172 to avoid further damage and maintain peak engine performance.

Fuel injectors are vital components that ensure your engine receives the right amount of fuel for efficient combustion. Ignoring the signs of a bad fuel injector can lead to more significant issues that not only affect performance but can also cause costly damage to your engine. Understanding what happens if you don’t replace a faulty fuel injector is key to maintaining your vehicle's health.

  • Poor Engine Performance

    • A malfunctioning fuel injector can cause your engine to misfire, idle roughly, or lose power. This can make driving difficult, especially during acceleration or under heavy loads.

  • Decreased Fuel Efficiency

    •  A bad fuel injector may not deliver the correct amount of fuel, causing your engine to burn more fuel than necessary. Over time, this leads to a significant drop in fuel economy, costing you more at the pump.

  • Increased Emissions

    •  When a fuel injector fails, it can throw off the air-fuel ratio in the engine, leading to higher emissions. This can cause your vehicle to fail emissions tests and contribute to environmental pollution.

  • Engine Damage

    • A leaking or malfunctioning injector can cause unburnt fuel to enter the engine cylinders, which may lead to engine knocking, overheating, or damage to the pistons and other engine components.

  • Clogged Catalytic Converter

    • Excess fuel from a faulty injector can lead to incomplete combustion, causing fuel to build up in the catalytic converter. This can result in a clogged or damaged catalytic converter, which is a costly repair.

  • Check Engine Light Activation

    • A bad fuel injector will trigger the check engine light. Ignoring this warning could lead to more severe problems down the road, as the onboard diagnostics are signaling a need for immediate attention.

Ignoring a bad fuel injector can lead to serious and expensive engine problems. From reduced fuel efficiency to potential engine damage, the consequences can be costly and time-consuming to fix. If you suspect a fuel injector issue, it’s best to address it promptly to avoid more severe and expensive repairs down the line. Regular maintenance and timely repairs are essential for keeping your engine running smoothly.
