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 OEM 0 445 010 834 high pressure fuel pump is designed specifically for the Nissan 5.0L Cummins diesel engine, used in the Titan XD from 2016 to 2019. This pump is a central component in the common rail fuel system, responsible for delivering fuel at high pressure to the injectors for precise combustion.

If you're experiencing hard starts, reduced throttle response, or diagnostic trouble codes related to fuel pressure, the high pressure pump may be the source of the issue.

Key Features of the OEM 0 445 010 834 Fuel Pump:

  • Precision Plunger Assembly
    • Generates the high pressure required for injector operation
  • Internal Fuel Metering Control
    • Delivers consistent pressure across load ranges
  • OEM-Specific Fitment
    • Designed to integrate with the Cummins 5.0L layout in the Nissan Titan XD
  • Robust Construction
    • Built to endure high operating temperatures and pressures
  • Supports Emissions Control
    • Works in sync with advanced engine calibration and SCR systems

Always confirm OEM part number 0 445 010 834 before ordering to ensure correct fit for your 2016–2019 Nissan Titan XD with the 5.0L Cummins diesel.

Technically, you might be able to drive for a short time with a failing high pressure fuel pump—but it’s not safe or recommended.

Modern fuel systems rely on precise fuel delivery, and the high pressure fuel pump (HPFP) is essential for that. When it starts to fail, it can cause erratic engine behavior and, in some cases, permanent damage.

Why Driving with a Bad HPFP Is Risky:

  • Unstable engine operation
    • You may experience stalling, surging, hesitation, or rough idling due to inconsistent fuel pressure.
  • Hard starting or no start
    • A failing HPFP may not supply enough pressure for the engine to start or run reliably.
  • Fuel starvation under load
    • You may notice bucking or sudden loss of power during acceleration or climbing hills.
  • Potential engine damage
    • Prolonged lean conditions caused by low fuel pressure can harm pistons, valves, or injectors.
  • Breakdown risk
    • A failing pump can stop working entirely without warning, leaving you stranded.

If you suspect a bad high pressure fuel pump, avoid long drives and have the vehicle diagnosed immediately. Addressing the issue early can prevent further damage and reduce repair costs.

It supplies high-pressure diesel fuel to the common rail injection system for precise fuel delivery and combustion.

Common symptoms include hard starting, loss of power, poor fuel economy, rough idle, and injector misfire codes.

Contaminated diesel, poor fuel filtration, or prolonged low-fuel conditions can lead to internal wear or pump damage.

Yes, it’s strongly recommended to flush the system and inspect fuel lines and injectors to avoid repeat contamination.
