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.

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 high-pressure fuel pump is a crucial component in a modern engine's fuel system. It's responsible for delivering pressurized fuel to the injectors, which then spray the fuel into the engine's combustion chamber. However, like any mechanical part, high-pressure fuel pumps can fail. In this article, we'll explore some of the common causes of high-pressure fuel pump failure.

  • Contaminated Fuel
    • One of the most common causes of high-pressure fuel pump failure is contaminated fuel. Dirt, debris, and other contaminants can enter the fuel system and damage the pump's internal components. In extreme cases, contaminated fuel can cause the pump to seize completely, resulting in a costly repair bill.
  • Lack of Lubrication
    • The high-pressure fuel pump relies on a constant flow of lubrication to keep its internal components moving freely. If the fuel system doesn't receive enough lubrication, the pump's components can wear down and eventually fail. This can happen if the engine oil isn't changed regularly or if the wrong type of oil is used.
  • Electrical Problems
    • Modern high-pressure fuel pumps are often electronically controlled, which means they rely on a complex network of sensors, wires, and connectors to function properly. If any of these components fail, the pump can stop working altogether. Common electrical problems include damaged wiring, faulty sensors, and blown fuses.
  • Overheating
    • High-pressure fuel pumps generate a lot of heat, which can cause the pump's internal components to expand and contract rapidly. Over time, this can cause the pump to warp or crack, leading to a loss of pressure and eventual failure. Overheating can be caused by a variety of factors, including a clogged fuel filter, a malfunctioning thermostat, or a faulty cooling system.
  • Wear and Tear

High-pressure fuel pumps can fail simply due to normal wear and tear. Over time, the pump's internal components can become worn or damaged, reducing its efficiency and eventually causing it to fail. Regular maintenance can help prevent wear and tear, but eventually, all pumps will need to be replaced.

In conclusion, high-pressure fuel pump failure can be caused by a variety of factors, including contaminated fuel, lack of lubrication, electrical problems, overheating, and normal wear and tear. By understanding these causes, you can take steps to prevent pump failure and keep your engine running smoothly. Regular maintenance, including oil changes, fuel filter replacements, and coolant flushes, can help extend the life of your high-pressure fuel pump and prevent costly repairs.

The pump is designed to meet Cummins’ exact performance specifications, delivering the precise fuel pressure required for modern high-performance diesel engines.

Risks include reduced engine efficiency, increased emissions, damage to fuel injectors, and potential engine stalling under load.

Early signs include difficulty starting, fluctuating fuel pressure readings, fuel leakage, and diagnostic trouble codes related to the fuel system.

Inspect fuel lines for blockages, check for contaminants in the fuel system, and ensure proper installation torque and alignment during replacement.
