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 Paccar MX-13 Fuel Injector 2024–2026: OEM 2461236PEX is a high-pressure, electronically controlled diesel fuel injector designed for use in Paccar MX-13 engines produced from 2024 through 2026. It is a key component of the engine’s common rail fuel system and is engineered to deliver fuel precisely and efficiently to each combustion chamber.
Fuel injectors like OEM 2461236PEX play a central role in how the engine manages combustion. They receive extremely high-pressure fuel from the common rail and, based on electronic commands from the engine control module (ECM), deliver measured amounts of fuel into the cylinders at exact timing intervals. The injector atomizes diesel fuel into a fine mist, which mixes thoroughly with compressed air for clean and efficient combustion.
Because it is built for modern MX-13 platforms, OEM 2461236PEX is engineered for tight tolerances, precise spray patterns, and reliable performance under heavy loads and harsh operating conditions typical of long-haul and vocational applications.
In summary, the Paccar MX-13 Fuel Injector OEM 2461236PEX is a critical fuel system component that:
- Delivers high-pressure fuel into the combustion chamber
- Is controlled electronically for precise timing and metering
- Supports efficient combustion and emissions control
- Is designed specifically for 2024–2026 MX-13 engine applications
This injector helps ensure stable engine operation, fuel efficiency, and compliance with modern emissions requirements in Paccar MX-13 powered vehicles.
You should replace your fuel injector when diagnostics confirm it is no longer delivering fuel correctly and repair or cleaning will not restore proper performance. Fuel injectors are precision components, and once they begin leaking, sticking, or flowing outside specification, replacement is often the most reliable solution.
Injector replacement becomes necessary when performance issues persist after verifying fuel quality, filter condition, and fuel pressure. Ignoring a failing injector can lead to engine damage, excessive smoke, oil dilution, and costly aftertreatment failures.
Midway through the evaluation process, the following conditions typically indicate fuel injector replacement is required:
- Persistent misfire on a specific cylinder
- Injector balance rates outside manufacturer specifications
- Hard starting or extended crank times
- Excessive black or white exhaust smoke
- Fuel dilution in engine oil
- Visible fuel leakage or confirmed internal sticking
- Repeated over-fueling or contribution fault codes
If metal contamination from a failing high-pressure fuel pump is found, multiple injectors may need replacement to prevent repeat failure. Always inspect fuel filters and check for debris before installing new injectors.
Fuel injector replacement should be based on verified testing results, not just symptoms. Addressing underlying fuel system or combustion issues before installing new injectors is critical to ensuring long-term reliability and preventing premature failure.
It is an OEM fuel injector designed to deliver precise fuel to the engine’s combustion chamber on Paccar MX13 engines.
It meters and delivers fuel from the high-pressure rail to each cylinder for combustion.
