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.

Fuel injectors play a crucial role in the functioning of your Cummins 8.3L engine, especially the OEM J948529 model used between 1998 and 2004. Understanding how this component works can help maintain your engine's efficiency and longevity.
The fuel injector’s primary function is to deliver fuel into the combustion chamber in precise amounts and at specific intervals. This ensures optimal combustion, which is vital for the engine's operation. The OEM J948529 fuel injector is designed to withstand the demanding environment of a diesel engine.
Key Functions of the OEM J948529 Fuel Injector:
- Precise Fuel Delivery
- Injects the exact amount of fuel needed for combustion.
- Atomization
- Breaks down fuel into fine droplets for efficient burning.
- Timing
- Delivers fuel at the right moment to maximize combustion efficiency.
- Pressure Regulation
- Maintains the required pressure for fuel injection.
To ensure your Cummins 8.3L engine runs smoothly, it’s essential to keep the fuel injectors clean and in good working condition. Signs of a malfunctioning injector include poor fuel economy, rough idling, and engine misfires.
A failed fuel injector can cause significant issues in your diesel engine, leading to reduced efficiency and potential engine damage. Recognizing the symptoms early can help you avoid costly repairs and downtime.
One of the most common signs of a failing fuel injector is poor engine durability. You may notice that your engine struggles to start or runs roughly, especially at idle. Additionally, decreased fuel efficiency can indicate that the injector is not delivering the proper amount of fuel.
Look out for these specific symptoms:
- Engine misfires
- Inconsistent or incomplete combustion due to faulty fuel delivery.
- Rough idling
- The engine runs unevenly while idling.
- Poor acceleration
- Sluggish response when you press the accelerator.
- Increased fuel consumption
- Using more fuel than usual for the same tasks.
- Black smoke from the exhaust
- Excessive fuel being burned inefficiently.
Ignoring these signs can lead to more severe problems, including damage to other engine components. Regular maintenance and timely replacement of faulty injectors are crucial to keep your diesel engine running smoothly.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy.
