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.

Diesel engines depend on precise airflow and boost monitoring to deliver smooth performance, efficient combustion, and reliable operation. A key part of that monitoring process is the pressure sensing tube, which connects critical pressure points to the engine’s sensor system. For Cummins ISB and ISL engines from 2017 to 2024, the Cummins ISB, ISL Pressure Sensing Tube 2017–2024: OEM 5505839 provides a factory-matched replacement that helps maintain proper pressure feedback and supports consistent engine response under real-world driving conditions.

    • The pressure sensing tube links intake or boost pressure sources to the engine’s sensor network,
      helping the electronic control module interpret pressure changes and adjust fuel and airflow accordingly.

    • The OEM 5505839 tube is engineered specifically for Cummins ISB and ISL engines produced between 2017 and 2024,
      ensuring correct fitment and seamless integration with original system components.

    • A properly routed and sealed sensing tube supports stable turbocharger behavior by delivering reliable boost pressure information,
      helping the engine maintain responsiveness during acceleration and load changes.

    • Installing the correct OEM pressure sensing tube reduces the likelihood of false sensor alerts or unintended fault codes,
      helping minimize unneeded diagnostic time and interruptions.

    • Replacing damaged or deteriorated tubing with the Cummins ISB, ISL Pressure Sensing Tube 2017–2024: OEM 5505839
      supports better turbo control, smoother idle, and steadier engine performance.

    • Choosing an OEM-grade component gives you confidence in durable construction, proper sealing, and long-term service life
      for everyday diesel operation.

The pressure sensing tube may be a small component, but it plays a big role in how your Cummins ISB or ISL engine interprets pressure data and responds on the road. The OEM 5505839 tube helps ensure your engine continues to receive dependable pressure inputs, aiding in consistent combustion, responsive performance, and fewer service interruptions. At Tamerx Diesel Parts, we offer quality diesel components to help keep your engine running reliably mile after mile.

A pressure sensing tube is a small but critical component in diesel emissions and exhaust monitoring systems. It allows sensors to measure pressure differences across components like the DPF or SCR. Because it operates in harsh exhaust conditions, the tube can become blocked or fail over time. Understanding the common causes helps prevent inaccurate readings and costly system issues.

  • Soot and carbon buildup: Exhaust particles can accumulate inside the tube, restricting airflow and pressure signals.

  • DEF crystallization deposits: In SCR systems, improper DEF dosing can create hardened deposits that block the tube.

  • Moisture or condensation: Water buildup can interfere with pressure readings and promote internal clogging.

  • Heat and vibration damage: High exhaust temperatures and constant vibration can cause cracking or weakening of the tube.

  • Improper installation or routing: Kinks, sharp bends, or loose connections can lead to failure or inaccurate measurements.

  • Sensor port contamination: Blocked pressure ports at the sensor or exhaust connection can mimic tube failure.

Pressure sensing tube blockage or failure is often caused by contamination or harsh operating conditions. Regular inspection and prompt replacement help ensure accurate pressure monitoring, proper regeneration, and reliable emissions system performance.

Although someone with mechanical experience can install it, professional installation of the Cummins ISB, ISL Pressure Sensing Tube 2017-2024: OEM 5505839 ensures proper routing and prevents leaks. A trained technician can also verify correct sensor function afterward.

The Cummins ISB, ISL Pressure Sensing Tube 2017-2024: OEM 5505839 connects between pressure ports and sensors within the ISB or ISL engine assembly. Its location allows it to transmit pressure readings accurately to the ECU.

The Cummins ISB, ISL Pressure Sensing Tube 2017-2024: OEM 5505839 is designed to withstand typical engine heat and vibration. Its OEM build quality supports consistent performance over extended use.

Installing a new Cummins ISB, ISL Pressure Sensing Tube 2017-2024: OEM 5505839 helps restore accurate pressure data to the control unit. This can lead to smoother engine response and better overall drivability.
