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.

A high-pressure oil pump is essential for ensuring your engine receives the proper amount of lubrication under varying loads and speeds. When a high-pressure oil pump fails, it can lead to serious engine damage, reducing performance and increasing the risk of costly repairs. Understanding the causes of high-pressure oil pump failure can help you maintain your engine and prevent unexpected breakdowns.

Common Causes of High-Pressure Oil Pump Failure:

  • Oil Contamination

    • Dirt, debris, and sludge in the oil can cause wear on the pump’s internal components. Contaminated oil can lead to clogging, which reduces the pump's efficiency and causes it to fail over time.

  • Lack of Maintenance

    • Skipping regular oil changes or using the wrong oil can result in poor lubrication, which increases friction and heat inside the pump. This accelerates wear and leads to pump failure.

  • Excessive Heat

    • Engines operating under extreme heat for long periods can cause the oil pump to overheat. Excessive heat reduces the oil’s ability to lubricate effectively, which puts more strain on the pump.

  • Low Oil Pressure

    • If the oil pressure in the engine is too low, it may cause the pump to work harder than necessary. This increased workload can cause premature failure of the high-pressure oil pump.

  • Worn or Damaged Seals

    • Over time, seals in the high-pressure oil pump can wear out or become damaged, leading to oil leaks. Insufficient oil flow can cause pump failure.

Preventing high-pressure oil pump failure starts with proper engine maintenance. Regular oil changes, using the correct oil, and keeping an eye on oil pressure can help ensure your pump lasts longer and keeps your engine running smoothly. If you notice signs of oil pump issues, like low oil pressure or unusual noises, addressing them quickly can save you from significant engine repairs.

Symptoms include long cranking, poor idle, loss of power, and low injection control pressure codes.

Yes, loss of injection pressure due to a weak pump can cause engine hesitation or shutdown under load.

Restoring proper oil pressure may lead to smoother injector operation, which can help improve fuel usage consistency.

No formal break-in is required, but using clean oil and monitoring performance during the first few hours is advised.
