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.

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 OEM ASP5410-6506713 DEF head unit is an essential part of the Diesel Exhaust Fluid (DEF) delivery system in Cummins engines equipped with Selective Catalytic Reduction (SCR) technology. This unit manages critical functions that help ensure compliance with emission standards and consistent operation in demanding environments.
Mounted on top of the DEF tank, this component monitors fluid levels and temperature while supporting DEF transfer to the SCR system. If it fails, common issues include inaccurate readings, system faults, or restricted engine operation.
Key features of the OEM ASP5410-6506713 DEF head unit include:
- Integrated Fluid Level Sensor
- Provides accurate tank level data
- Heating Element
- Prevents DEF from freezing in cold temperatures
- Temperature Probe
- Supports proper system regulation and dosing
- OEM-Style Connector
- Ensures seamless communication with the vehicle's ECM
- Tank-Mounted Design
- Built to fit Cummins DEF tanks without modification
Before replacement, verify your application and ensure the OEM part number ASP5410-6506713 matches your existing unit.
This DEF head is suited for Cummins-powered trucks, buses, and off-road equipment operating in environments where emissions compliance and durability are critical.
If your DEF (Diesel Exhaust Fluid) head unit has failed, it can trigger warning lights, reduce engine function, or eventually lead to a no-start condition. Addressing the issue quickly is essential to avoid downtime or further complications.
Steps to Take:
- Check for Error Codes
- Use a diagnostic scan tool to confirm that the DEF head unit is the source of the problem. Common codes include issues related to fluid level sensors, temperature sensors, or communication faults.
- Inspect DEF Fluid Quality
- Contaminated or old DEF can trigger system faults. Make sure the DEF is fresh and meets ISO 22241 standards. Cloudy or crystallized fluid may indicate contamination.
- Look for Physical Damage
- Examine the head unit and connectors for corrosion, moisture, or broken wiring. Road salt and harsh weather can affect connectors and cause sensor failure.
- Contact a Diesel Technician or Dealer
- Replacement may be necessary if the unit has failed electronically or internally. Many DEF systems require reprogramming after installation.
- Do Not Bypass the System
- Tampering with or deleting emissions systems is illegal in most areas and may void warranties.
Proper DEF system maintenance—using clean DEF, checking levels regularly, and keeping components free from debris—can help prevent future failures.
The ASP5410-6506713 manages DEF suction, level detection, temperature sensing, and integrated heating for Cummins SCR systems.
It is built for harsh environments, including vibration, extreme temperatures, and exposure to DEF crystallization.
While calibration isn’t required, improper sealing or orientation can lead to DEF leaks or incorrect sensor readings.
It should be checked during scheduled emissions system maintenance or immediately if DEF-related faults appear.
