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.

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 customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.
The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more.
You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation.
Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.
All fluids must be drained.
If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.
Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.

The Iveco FPT Doser DEF Pump: OEM 84246892R is a Diesel Exhaust Fluid (DEF) supply pump used in engines equipped with a Selective Catalytic Reduction (SCR) emissions system. Its primary function is to move and pressurize DEF from the storage tank to the dosing injector in the exhaust system.
This pump is part of the aftertreatment system found in Iveco and FPT-powered applications. It ensures that DEF is delivered at the correct pressure and volume so it can be accurately injected into the exhaust stream. Once injected, DEF helps reduce nitrogen oxide emissions through a chemical reaction inside the SCR catalyst.
OEM 84246892R is engineered to integrate with the engine control unit (ECU), which monitors emissions levels and regulates how much DEF is required based on operating conditions. The pump responds to these commands to maintain proper system operation.
Key characteristics of the Iveco FPT DEF pump include:
- Supplies and pressurizes DEF for the SCR system
- Works in coordination with the ECU and dosing injector
- Designed for compatibility with Iveco and FPT engines
- Supports emissions compliance and exhaust treatment
In summary, OEM 84246892R is a critical emissions control component that ensures consistent DEF delivery, helping engines operate within required environmental standards.
Prolonging the lifespan of your DEF doser pump starts with protecting the DEF system from contamination and crystallization. The doser pump is responsible for pressurizing Diesel Exhaust Fluid and delivering it to the injector, so clean fluid and proper system maintenance are critical to long-term reliability.
The most important factor is using high-quality DEF that meets ISO 22241 standards. Poor-quality or contaminated DEF can damage internal pump components and cause crystallization inside the pump and lines. Always store DEF in sealed containers, away from heat and direct sunlight.
Midway through routine service and inspections, focus on these best practices:
- Use only certified DEF from reputable suppliers
- Keep DEF containers and filling equipment clean
- Avoid mixing DEF with water or other fluids
- Replace DEF filters (if equipped) at recommended intervals
- Inspect tank, lines, and fittings for crystallization buildup
- Allow proper shutdown cycles so the system can purge
It is also important to avoid running the DEF tank completely dry, as this can introduce air into the system and stress the pump. Address SCR, dosing, or pressure fault codes immediately to prevent additional strain on the pump motor.
In most cases, DEF doser pump failure is caused by contamination or neglected maintenance rather than normal wear. Consistent DEF quality control, clean handling practices, and early correction of system issues are the most effective ways to extend pump lifespan and maintain reliable SCR performance.
