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.

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 Volvo Mack D12 Fuel Injector (OEM 20564425) is responsible for delivering the correct amount of fuel into the engine for efficient combustion. Because fuel injectors operate under extremely high pressure and tight tolerances, proper maintenance is essential for maximizing their lifespan and maintaining reliable engine performance.

While the injector itself requires very little direct maintenance, keeping the fuel system clean and well-maintained can significantly reduce wear and help prevent premature failure.

Tips to Help Extend the Life of Your Fuel Injector

  • Use clean, high-quality diesel fuel
    • Quality fuel helps reduce deposits and contamination that can affect injector performance over time.
  • Replace fuel filters at the recommended intervals
    • Clean fuel filters prevent dirt, water, and other contaminants from reaching the injector and causing internal damage.
  • Drain water from the fuel system when necessary
    • Water contamination can lead to corrosion and reduce the service life of the injector and other fuel system components.
  • Keep the fuel system clean
    • Avoid introducing dirt or debris during maintenance or refueling, as even small particles can affect injector operation. Cleanliness is especially important when working on injectors. 
  • Address engine performance issues early
    • Hard starting, rough idling, excessive smoke, poor fuel economy, or reduced power may indicate injector or fuel system problems that should be inspected promptly. 
  • Inspect for leaks during routine maintenance
    • Fuel leaks around the injector or related seals should be repaired as soon as possible to prevent additional engine damage.
  • Avoid running with contaminated fuel
    • If poor-quality or contaminated fuel is suspected, have the fuel system inspected and serviced before continuing normal operation.
  • Follow the manufacturer's maintenance schedule
    • Regular engine service, including fuel filter replacement and routine fuel system inspections, helps create the best operating conditions for the injector.

The Volvo Mack D12 Fuel Injector (OEM 20564425) plays a vital role in delivering precise fuel for efficient combustion. By using clean fuel, replacing fuel filters on schedule, maintaining a clean fuel system, and addressing small issues before they become major problems, you can help extend the injector's lifespan and support reliable performance from your Volvo Mack D12 engine.

Yes, a bad fuel injector can significantly affect your engine's performance. Fuel injectors are responsible for delivering the correct amount of fuel into each cylinder at the proper time. When one or more injectors fail, become clogged, or leak, the engine may not receive the precise fuel needed for efficient combustion.

If left unresolved, a faulty fuel injector can reduce engine efficiency and potentially lead to more expensive repairs.

Here are some of the ways a bad fuel injector can affect engine performance:

  • Reduced acceleration
    • An injector that isn't delivering enough fuel can make the engine feel sluggish and less responsive during acceleration.
  • Engine misfires
    • Uneven fuel delivery can cause one or more cylinders to misfire, resulting in rough engine operation and noticeable vibrations.
  • Rough idling
    • A failing injector may disrupt the air-fuel mixture, causing the engine to idle unevenly or shake while stopped.
  • Poor fuel economy
    • A leaking or malfunctioning injector can deliver too much or too little fuel, increasing fuel consumption.
  • Hard starting
    • If the injector cannot supply the proper amount of fuel during startup, the engine may crank longer than normal or become difficult to start.
  • Excessive exhaust smoke
    • A rich fuel mixture caused by a leaking injector can produce black exhaust smoke, while poor combustion may increase emissions.
  • Check engine light
    • The engine control module may detect injector-related problems and store diagnostic trouble codes, illuminating the check engine light.

Addressing a bad fuel injector early can help restore smooth engine operation, improve fuel efficiency, and prevent damage to other fuel system or engine components. If you notice any of these symptoms, having the fuel system inspected promptly is the best way to avoid more extensive repairs.

Technicians commonly inspect the injector when diagnosing rough idle, engine misfires, excessive smoke, poor fuel economy, loss of power, fuel leakage, or injector-related diagnostic trouble codes.

Yes. Dirt, water, or other contaminants in the fuel system can accelerate injector wear, restrict fuel flow, or interfere with proper spray patterns, potentially affecting engine operation.

Yes. The OEM 20564425 is manufactured to Volvo and Mack specifications, providing direct compatibility with the original cylinder head, fuel system, and engine management components.

Technicians should inspect the injector bore, sealing surfaces, fuel lines, electrical connector, injector harness, valve cover components, and related fuel system parts to ensure proper installation.
