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 world of common-rail diesel systems, the high-pressure fuel rail is one of those critical components that silently shapes engine performance and reliability. For Dodge Ram trucks equipped with the Cummins 5.9L from years 2003 to 2007, the OEM high-pressure fuel rail (Bosch 0 445 226 014) is built to withstand extreme pressures, deliver stable fuel supply to injectors, and maintain consistency across all cylinders. When it falls short, you’ll start to feel the symptoms—even if your diagnostic tools don’t immediately point to the rail itself.

  • Channels fuel pressurized by the HP pump to each injector port, enabling synchronized and uniform fuel delivery

  • Maintains stable pressure under load, allowing injectors to perform clean, accurate atomization of fuel

  • Helps avoid symptoms like hard starting, black smoke, poor fuel economy, or rough idle that arise when the rail leaks or loses structural integrity

  • Built with precision tolerances to avoid pressure drop, pulses, or cavitation under high demand

  • Designed for direct OEM fit and compatibility on 2003–2007 5.9L Cummins systems

Because the high-pressure fuel rail is under constant strain and operates in a hostile environment (heat, vibration, extreme pressure), micrometric gaps or leaks can degrade performance long before they cause a catastrophic failure. Using the correct OEM 0 445 226 014 rail restores the structural integrity of your high-pressure circuit and safeguards the precision delivery system your engine depends on. In short: when your injectors need stable, high-pressure fuel, your rail must deliver without compromise.

The high-pressure fuel rail is a critical component in modern diesel and gasoline engines, ensuring fuel is delivered to the injectors at the correct pressure. Because it operates under extreme conditions, periodic inspection and maintenance are essential to prevent leaks, performance loss, and costly fuel system damage. Knowing when to inspect or service it helps keep your engine running efficiently and reliably.

Recommended Inspection and Service Intervals

  • Regular Maintenance Checks
    Inspect the fuel rail during every scheduled service or oil change for visible signs of wear, leaks, or corrosion.

  • Mileage-Based Inspection
    Most manufacturers recommend a detailed inspection every 60,000 to 100,000 miles, depending on driving conditions and fuel quality.

  • Fuel Quality Concerns
    If contaminated or poor-quality fuel is used, have the system inspected more frequently to prevent clogging or corrosion inside the rail.

  • Injector or Pump Replacement
    Always inspect the fuel rail whenever injectors or the high-pressure fuel pump are serviced, since metal shavings or debris may enter the system.

  • Leak or Pressure Issues
    Any signs of fuel leaks, poor starting, or loss of power should trigger an immediate inspection, regardless of mileage.

  • Heavy-Duty or Harsh Environments
    Vehicles operating in dusty, hot, or high-load conditions may require shorter service intervals to ensure reliability.

The high-pressure fuel rail should be inspected regularly as part of your vehicle’s preventive maintenance routine. Early detection of leaks or pressure irregularities helps protect injectors, maintain fuel efficiency, and prevent expensive repairs. Staying proactive with inspections ensures your fuel system operates smoothly and your engine remains dependable for the long haul.

You might see erratic fuel rail pressure readings, misfires, low power, or fuel leaks.

Dirt or debris inside the rail can plug injector ports, damage injector tips, or cause pressure fluctuations.

Fuel leakage reduces system pressure, causes lean conditions, and may lead to injector or pump damage.

The exterior may be cleaned, but internal surfaces must be free of deposits — often replacement is safer for internal damage.
