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 Cummins ISB / ISL Pressure Sensing Tube (OEM 5418632) functions as a critical pathway that allows pressure data to be transmitted from the exhaust system to the engine’s sensors. Although it’s a simple tube in design, it plays a key role in helping the engine monitor and respond to changing conditions within the aftertreatment system.
This component is typically connected to areas around the diesel particulate filter (DPF). It carries pressure signals from different points in the exhaust stream to a differential pressure sensor, which then relays that information to the engine control module (ECM).
Here’s how it works step by step:
- Captures pressure from the exhaust system
- The tube is positioned at specific points before and after components like the DPF to measure pressure differences.
- Transfers pressure signals to the sensor
- Instead of electrical signals, the tube physically channels pressure to the differential pressure sensor for measurement.
- Enables calculation of soot levels
- By comparing pressure readings, the system can determine how much soot has accumulated inside the DPF.
- Communicates data to the ECM
- The sensor sends this information to the ECM, which uses it to make decisions about system operation.
- Triggers maintenance actions when needed
- If pressure differences indicate buildup, the ECM can initiate regeneration or alert the operator to potential issues.
In essence, the Cummins 5418632 pressure sensing tube works as a direct link between the exhaust system and the engine’s monitoring system, allowing accurate pressure data to guide critical decisions for emissions control and overall system operation.
Pressure sensing tubes don’t typically have a fixed replacement interval, so they should be replaced based on condition rather than mileage. The right time to replace one is when it becomes blocked, damaged, or unable to provide accurate readings.
Because this component plays a key role in monitoring pressure within the system, even a minor issue can lead to incorrect data and affect overall operation.
Here are common signs that indicate it’s time for a replacement:
- Persistent fault codes or warning lights
- If the system continues to trigger pressure-related codes even after clearing them, the tube may be restricted or failing.
- Visible blockage or buildup
- Heavy soot or residue inside the tube can restrict airflow and prevent accurate pressure readings.
- Cracks, brittleness, or physical damage
- Exposure to heat over time can weaken the material, making it prone to cracking or breaking.
- Kinks or restricted airflow
- A bent or pinched tube can limit proper pressure transmission, leading to incorrect sensor feedback.
- Repeated regeneration or system issues
- In diesel applications, inaccurate readings may cause frequent or failed regeneration cycles.
Regular inspection can help identify these issues early. Replacing a faulty pressure sensing tube at the right time helps maintain accurate system readings and prevents further complications.
It delivers pressure feedback related to airflow or exhaust conditions, which the ECU uses to regulate various engine functions and maintain system balance.
A damaged or disconnected tube can cause incorrect pressure readings, leading to fault codes, irregular engine behavior, or improper emissions system operation.
It is commonly made from durable materials such as stainless steel or reinforced tubing to withstand high temperatures, pressure changes, and vibration in engine environments.
Accurate pressure feedback helps ensure proper operation of emissions control systems by maintaining correct exhaust flow and system coordination.
