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.

Understanding how these injectors function and how to maintain them can help prevent engine issues and keep your truck running efficiently.

Key Functions of the Mack MP8 Fuel Injector

  • Precise Fuel Delivery
    • Each injector ensures that the right amount of fuel is delivered to the engine’s combustion chamber, promoting efficient fuel use and combustion.
  • Improves Fuel Economy
    • With accurate fuel injection, the engine burns fuel more efficiently, leading to better fuel economy and reduced operational costs.
  • Reduces Emissions

Maintenance Tips for Mack MP8 Fuel Injectors

  • Regular Cleaning

  • Monitor Fuel Efficiency
    • A sudden drop in fuel efficiency may indicate a problem with one or more injectors. Addressing this early can prevent further issues.
  • Check for Leaks
    • Inspect for fuel leaks around the injectors, which could cause a loss of pressure and reduced engine performance.
  • Replace When Necessary
    • If your engine experiences rough idling, misfires, or loss of power, it may be time to replace the injectors with OEM 85020428 to restore proper performance.

The Mack MP8 Fuel Injector (OEM 85020428) set of six plays a crucial role in ensuring precise fuel delivery, improving fuel economy, and reducing emissions. Regular maintenance and timely replacement of injectors will help keep your engine running smoothly and efficiently.

Fuel injectors are responsible for delivering the right amount of fuel to your engine's combustion chamber. When a fuel injector goes bad, it can cause a variety of performance issues, affecting your vehicle's efficiency and overall drivability. Recognizing the signs of a failing fuel injector is crucial to maintaining your engine's performance and avoiding more costly repairs.

Common Issues When a Fuel Injector Fails:

  • Engine Misfires

    • A bad fuel injector can cause your engine to misfire. This happens because the injector isn't supplying the proper amount of fuel, which leads to incomplete combustion.

  • Poor Fuel Efficiency

    • When a fuel injector goes bad, the engine may burn more fuel than necessary. This is due to the injector not delivering the correct amount of fuel, which reduces your vehicle’s fuel economy.

  • Rough Idling

    •  A failing fuel injector can cause the engine to run rough while idling. This is often a sign of an uneven fuel flow, making the engine vibrate or stutter when it’s not under load.

  • Engine Stalling

    •  In severe cases, a bad fuel injector may cause the engine to stall or struggle to maintain power, especially at low speeds or idle, due to improper fuel delivery.

  • Check Engine Light

    • A faulty fuel injector can trigger the check engine light. The vehicle’s onboard computer detects the imbalance in fuel delivery and alerts the driver to a potential issue.

  • Fuel Leaks

    • In some cases, a damaged fuel injector may leak fuel, which can result in a noticeable fuel smell around the vehicle or visible fuel stains.

When a fuel injector goes bad, it can lead to several engine issues, including misfires, poor fuel efficiency, and even engine stalling. If you notice any of these symptoms, it’s important to have your fuel injectors inspected and repaired as soon as possible. Timely maintenance and fuel system checks can help you avoid major engine problems and keep your vehicle running smoothly.

Contamination can cause irregular spray patterns, poor performance, and misfires.

Common symptoms include hard starts, rough idle, and unexpected drops in fuel economy.

Proper fuel delivery helps reduce wear on engine components, extending engine life.

Water, debris, or low-quality fuel can lead to wear of the nozzle and sealing surfaces.
