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.

A properly functioning aftertreatment system depends on accurate pressure feedback and secure connections between components. The Cummins aftertreatment hose (pressure sensing tube) plays a key role by carrying pressure signals from the exhaust system to sensors and the engine control module (ECM). This allows the system to monitor exhaust conditions and make precise adjustments that support emissions control and engine operation.

  • Transmits Pressure Signals to Sensors
    The hose carries pressure data from specific points in the exhaust or intake system to sensors, helping the ECM monitor system conditions accurately.
  • Supports Accurate Engine and Emissions Control
    With reliable pressure readings, the ECM can adjust fuel delivery, airflow, and aftertreatment functions to maintain balanced performance.
  • Essential for DPF and SCR System Monitoring
    Pressure data helps determine soot levels and exhaust flow, allowing systems like the DPF and SCR to function properly and trigger regeneration when needed.
  • Designed for Cummins Applications (2018–2024)
    Built to OEM 5418632 specifications, this hose is engineered for compatibility with Cummins engines, ensuring proper routing and integration within the aftertreatment system.
  • Durable Construction for Harsh Environments
    Made from high-quality materials, the hose is designed to withstand heat, vibration, and continuous use in demanding diesel exhaust conditions.

The aftertreatment hose may be a small component, but it plays a critical role in system accuracy and performance. In Cummins engines, a dependable hose ensures precise pressure feedback, supports emissions control, and helps keep the entire aftertreatment system operating smoothly.

Aftertreatment hoses are essential for carrying pressure signals or fluids between components like the DPF, SCR system, and related sensors. These hoses help ensure accurate readings and proper emissions control. When a hose develops a leak, it can interfere with system performance and lead to incorrect data being sent to the engine control module.

  • A leak can cause inaccurate pressure readings, which may disrupt DPF regeneration and overall exhaust system operation.
  • The check engine light or emissions warning may appear due to faulty sensor input.
  • The vehicle may enter reduced power or derate mode if the system detects ongoing emissions issues.
  • DEF-related hose leaks can affect proper dosing, leading to SCR system inefficiency.
  • Exhaust leaks can result in soot buildup around connection points and potential exposure to hot gases.
  • Continued operation with a leak can place added stress on aftertreatment components and lead to more extensive repairs.

While the vehicle may still be drivable for a short time, it is not recommended to continue driving with a leaking aftertreatment hose. Prompt repair helps maintain accurate system performance, prevent further damage, and ensure reliable emissions control.

 

It helps contain and direct flow without allowing leaks or pressure loss.

Yes, physical damage can cause leaks or disrupt flow.

A loose hose can lead to leaks and reduced system performance.

Yes, periodic inspection helps ensure it remains in good condition.
