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 Ford Powerstroke 7.3L engine, produced from 1999 to 2003, relies heavily on the high-pressure oil pump (HPOP) and the Injection Pressure Regulator (IPR) valve to maintain its efficiency and reliability. Understanding these components can help you ensure your engine runs smoothly.

The HPOP is crucial in delivering the necessary oil pressure to operate the fuel injectors. This oil pump is designed to generate and regulate high oil pressure, which is vital for the proper functioning of the fuel injectors. The main components of the HPOP include:

  • Reservoir
    • Stores the oil before it's pressurized.
  • Pump
    • Pressurizes the oil for injector operation.
  • Regulator
    • Maintains the required pressure levels.
  • Seals and O-rings
    • Ensure no oil leakage occurs.

The IPR valve plays a key role in regulating the oil pressure generated by the HPOP. It adjusts the pressure to ensure the injectors receive the correct amount for optimal functioning. Key components of the IPR valve are:

  • Valve body
    • Controls the oil flow.
  • Solenoid
    • Activates the valve to regulate pressure.
  • O-rings
    • Provide seals to prevent oil leaks.

Regular inspection and maintenance of these components can prevent common issues such as oil leaks, erratic idling, and poor fuel economy. For top-quality replacement parts, consider Tamerx Diesel Products to keep your engine running efficiently.

A faulty High Pressure Oil Pump (HPOP) and Injection Pressure Regulator (IPR) Valve can lead to significant issues in diesel engines. Identifying the symptoms early can prevent extensive damage and costly repairs. Here’s what to look for:

  • Starting Problems
    • One of the most common signs of a failing HPOP or IPR Valve is difficulty starting the engine. If your diesel engine takes longer to start or doesn’t start at all, it could indicate a problem with these components.
  • Erratic Engine 
    • When the HPOP or IPR Valve fails, the engine might run erratically. You might notice:
      • Rough idling
      • Stalling
      • Surging
    • These symptoms occur because the fuel injection system is not receiving the correct oil pressure.
  • Loss of Power
    • A significant drop in engine power is another red flag. If your vehicle struggles to accelerate or maintain speed, the HPOP or IPR Valve could be at fault. This happens because the fuel injectors are not getting enough pressure to function correctly.
  • Check Engine Light
    • The Check Engine Light (CEL) might illuminate if there are issues with the HPOP or IPR Valve. A diagnostic scan can reveal specific error codes related to these components.
  • Unusual Noises
    • Listen for unusual noises such as knocking or ticking. These sounds can indicate that the oil pump is not delivering adequate pressure, leading to improper engine lubrication.

By recognizing these signs early, you can ensure timely maintenance and avoid further complications. If you suspect a problem with your HPOP or IPR Valve, consult a professional mechanic for a thorough inspection and necessary repairs.

Yes, monitoring ICP values and IPR duty cycle can help pinpoint issues with pressure buildup or valve response.

The HPOP supplies oil pressure to operate the injectors, while the IPR valve regulates that pressure based on engine demands.

Symptoms include hard starting, long cranking, engine stalls, and injection control pressure-related fault codes.

Depending on experience and access, installation usually takes between 3 to 5 hours.
