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 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 works as a key component of the Selective Catalytic Reduction (SCR) system, delivering Diesel Exhaust Fluid (DEF) from the storage tank to the exhaust stream in a controlled and pressurized manner.

This pump is responsible for drawing DEF from the tank, filtering it, and building the correct pressure required for accurate dosing. The engine control unit (ECU) continuously monitors operating conditions such as engine load, exhaust temperature, and nitrogen oxide levels. Based on this data, the ECU commands the DEF pump to supply the precise amount of fluid needed.

Here’s how the system operates step by step:

  • DEF is pulled from the storage tank into the pump
  • The pump pressurizes the fluid to the required level
  • The ECU regulates pump output based on emissions demand
  • Pressurized DEF is delivered to the dosing injector
  • DEF is sprayed into the exhaust stream upstream of the SCR catalyst

Once injected into hot exhaust gases, DEF breaks down into ammonia. Inside the SCR catalyst, ammonia reacts with nitrogen oxide emissions and converts them into nitrogen and water vapor before exiting the exhaust system.

OEM 84246892R ensures accurate DEF delivery, which is essential for maintaining emissions compliance. A properly functioning DEF pump helps prevent warning lights, system derates, and emissions-related downtime in Iveco and FPT-powered applications.

When your DEF doser pump is failing, quick diagnosis is essential to prevent SCR efficiency faults, engine derates, and costly emissions repairs. The DEF pump is responsible for building and maintaining the pressure needed to deliver Diesel Exhaust Fluid to the dosing injector. If it cannot maintain proper pressure, the SCR system cannot function correctly.

The first step is to perform a full diagnostic scan and review DEF pressure readings, pump duty cycle, and related fault codes. Compare commanded pressure to actual pressure to determine whether the pump is weak, restricted, or electrically faulty.

Midway through troubleshooting, focus on these critical checks:

  • Verify DEF quality meets ISO 22241 standards
  • Inspect for crystallization in the DEF tank and lines
  • Check DEF filter condition (if equipped)
  • Inspect wiring harness and connectors for corrosion or damage
  • Confirm proper voltage supply and ground to the pump
  • Test for pressure loss or inability to hold prime

If contamination or crystallization is present, flush the DEF tank and lines before installing a new pump. Installing a replacement without cleaning the system can quickly damage the new unit.

If the pump fails pressure tests, self-diagnostics, or shows internal leakage, replacement is typically required. Always correct the root cause, such as poor DEF quality or electrical faults, to prevent repeat failure and ensure reliable SCR system performance.
