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.

Efficient emissions control depends on accurate data and proper system connections—and that’s where the aftertreatment hose comes in. This component acts as a pressure sensing pathway within the exhaust system, helping relay critical information between components and sensors. In Cummins applications, the hose plays an important role in maintaining consistent system communication and supporting overall aftertreatment performance.

  • Transfers Pressure Data Across the System
    The hose functions as a pressure sensing tube, allowing exhaust pressure readings to travel between components and sensors for accurate monitoring.
  • Supports Accurate Sensor Feedback
    By maintaining a clear and stable connection, the hose helps ensure sensors provide reliable readings to the engine control module (ECM), supporting proper system adjustments.
  • Plays a Role in DPF and SCR Operation
    Pressure data is essential for monitoring soot levels and exhaust flow, helping systems like the DPF and SCR function correctly within the aftertreatment process.
  • Designed for Cummins Engines (2018–2024)
    Built to OEM 5507274 specifications, this hose is intended for compatibility with Cummins engines and their factory-installed aftertreatment systems.
  • Durable Construction for Exhaust Environments
    Made to handle heat, vibration, and continuous operation, the hose is designed to perform reliably in demanding diesel applications.

The aftertreatment hose may be a small part of the system, but it plays a big role in keeping everything connected and functioning properly. In Cummins engines, a dependable hose helps maintain accurate pressure readings, supports emissions control, and keeps the aftertreatment system running smoothly over time.

Aftertreatment hoses are responsible for carrying pressure signals or fluid between key emissions components such as the Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR) system, and related sensors. When one of these hoses begins to leak, it can affect how the system monitors and controls emissions. While the vehicle may still be drivable, continuing to operate with a leak can lead to additional issues.

  • A leaking hose can cause inaccurate pressure readings, which may disrupt DPF regeneration cycles and overall system performance.
  • Warning lights such as the check engine or emissions system alert may appear due to incorrect sensor data.
  • Reduced engine performance or derate mode may occur if the system detects an ongoing emissions fault.
  • Exhaust leaks or DEF-related hose leaks can lead to contamination or improper dosing in the SCR system.
  • Over time, unresolved leaks can place additional strain on other aftertreatment components, leading to more costly repairs.
  • In some cases, visible damage or disconnection can worsen quickly due to heat and vibration.

Driving short distances may be possible, but it is not recommended to ignore a leaking aftertreatment hose. Prompt inspection and repair help maintain accurate system readings, ensure proper emissions control, and prevent further damage to the exhaust system.

Damage can lead to leaks, which may reduce system efficiency.

It is built to withstand pressure from fluid or gas movement within the system.

Yes, exposure to heat and stress can cause wear or cracking.

Signs may include leaks, visible cracks, or reduced system performance.
