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. 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 Mack MP7 Fuel Injector (OEM 85020427) plays a crucial role in the engine’s fuel system, ensuring efficient combustion and power delivery. These injectors are designed to precisely control the fuel injection process, ensuring optimal engine function and fuel efficiency.
Here’s how these fuel injectors work:
- Fuel Delivery
- The injectors receive pressurized fuel from the fuel pump, ensuring a consistent flow.
- Precise Injection
- Each injector sprays fuel into the engine's combustion chamber at a specific timing, atomizing the fuel for thorough mixing with air.
- Control via ECM
- The engine control module (ECM) regulates the injector's opening and closing to optimize combustion.
- High Pressure
- These injectors operate under high pressure, allowing fine fuel misting for complete combustion.
Properly functioning injectors lead to better fuel economy, smoother engine operation, and reduced emissions. Over time, injectors may become clogged or worn, impacting engine efficiency. Regular maintenance can help extend their lifespan and prevent issues.
Mack MP7 injectors are engineered for durability and reliability, making them an essential component in maintaining engine health. If you notice symptoms like hard starting, rough idling, or poor fuel economy, it might be time to inspect your injectors.
A fuel injector plays a crucial role in delivering fuel to your engine. When it goes bad, you might wonder if it’s safe to continue driving. While driving with a bad fuel injector is possible, it can lead to serious issues over time.
Symptoms of a bad fuel injector can range from rough idling to poor fuel economy. If left unaddressed, the injector's problems could affect the engine's condition. Here’s what you might experience if you drive with a malfunctioning fuel injector:
- Loss of Power
- The engine may feel weak, particularly during acceleration or climbing hills.
- Increased Fuel Consumption
- A bad injector can lead to inefficient fuel use, resulting in more frequent trips to the gas station.
- Rough Idling
- The engine may run roughly, especially when stopped or idling.
- Engine Misfires
- Frequent misfires could occur, making driving feel jerky and unstable.
If you suspect a faulty fuel injector, it’s advisable to address the issue promptly. Continuing to drive can result in more damage, potentially leading to costly repairs. Replacing or repairing the injector can help maintain your vehicle's reliability and longevity.
Over-fueling can result in excessive black smoke, poor fuel economy, and carbon buildup in the exhaust system or on the injector tips.
Yes, white smoke can be a sign of poor fuel combustion or a leaking injector nozzle delivering unburned diesel.
You can verify compatibility by checking your engine’s serial number against OEM part lookup tools or dealer-provided reference lists.
While light exterior cleaning is possible, internal wear and calibration issues mean replacement is the recommended solution for consistent performance.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy.
