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.

In the Mack MP7 and MP8 engines, the OEM 85103778 fuel pump plays a crucial role in maintaining engine efficiency and performance. In this blog, we’ll focus on how the fuel pump works and why it’s essential to keep it in top condition.

Key Functions of the Mack MP7, MP8 Fuel Pump (OEM 85103778):

  • Ensures Consistent Fuel Delivery

    • The fuel pump ensures that the engine receives the correct amount of fuel under various load conditions, allowing for smooth and efficient engine operation.

  • Maintains Optimal Fuel Pressure

    • This fuel pump regulates fuel pressure to the injectors, ensuring precise fuel injection and maintaining engine efficiency, which is critical for both performance and fuel economy.

  • Prevents Engine Stalling or Power Loss

    • A malfunctioning fuel pump can lead to inconsistent fuel flow, causing issues such as engine stalling or power loss. The OEM 85103778 pump prevents these problems by delivering fuel at the right pressure and volume.

  • Supports Clean Combustion

    • With accurate fuel delivery, the pump helps achieve proper fuel combustion, reducing harmful emissions and supporting the engine’s overall environmental performance.

  • Designed for Mack MP7 and MP8 Engines

    • Specifically designed for Mack MP7 and MP8 engines, the OEM 85103778 fuel pump is built to ensure a perfect fit and reliable performance for 2008-2016 models.

The Mack MP7, MP8 Fuel Pump (OEM 85103778) is essential for maintaining efficient fuel delivery, engine performance, and fuel economy. Regular maintenance or timely replacement of the fuel pump ensures that your engine operates smoothly and reliably. At TamerX Diesel Parts, we provide high-quality OEM fuel pumps to help you keep your Mack MP7 or MP8 engine running at its best.

The fuel pump is an essential part of your vehicle’s fuel system, responsible for delivering fuel from the tank to the engine. When the fuel pump begins to fail, it can cause a variety of performance issues that may lead to engine damage if not addressed. In this blog, we’ll explore what happens when a fuel pump goes bad and the common symptoms you should watch out for.

Symptoms of a Failing Fuel Pump:

  • Difficulty Starting the Engine

    • One of the earliest signs of a failing fuel pump is trouble starting the engine. If the pump isn’t providing enough fuel pressure, the engine may crank for longer periods before starting or may fail to start altogether.

  • Loss of Power

    • A malfunctioning fuel pump can lead to a noticeable loss of power, especially when accelerating or driving uphill. The engine may feel sluggish and struggle to maintain speed under load.

  • Engine Stalling

    • If the fuel pump cannot consistently deliver fuel, the engine may stall while driving. This can happen at any speed, but it’s especially dangerous if it occurs at higher speeds.

  • Poor Fuel Efficiency

    • A bad fuel pump may cause an imbalanced fuel-to-air mixture, resulting in poor fuel efficiency. You may notice that you need to refuel more often than usual.

  • Whining Noise from the Fuel Tank

    •  A failing fuel pump may produce a high-pitched whining sound, often noticeable from the rear of the vehicle where the fuel tank is located. This sound can indicate that the pump is struggling to operate properly.

  • Check Engine Light

    • A bad fuel pump can trigger the check engine light, indicating a problem with fuel delivery. A diagnostic scan can pinpoint the issue and confirm if the fuel pump is to blame.

When a fuel pump goes bad, it can lead to engine starting problems, loss of power, stalling, and poor fuel efficiency. Recognizing these symptoms early is key to preventing further damage and avoiding costly repairs. If you suspect your fuel pump is failing, it’s important to have your vehicle inspected and repaired promptly to ensure optimal performance and safety. Regular maintenance can help extend the life of your fuel system and keep your vehicle running smoothly.
