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.

For model years 2016 to 2019, the Nissan Titan XD equipped with the Cummins 5.0 L V8 diesel engine utilizes the OEM Bosch 0 445 218 026 high-pressure fuel rail. This part serves as the passenger-side (right side) fuel distribution component in the engine’s common rail fuel injection system. It plays a critical role in maintaining consistent, high-pressure diesel flow to each injector, supporting precise fuel delivery and clean combustion.

  • Additional Notes

Replacing this rail with a genuine Bosch 0 445 218 026 unit ensures fuel system stability and proper injector operation. If experiencing hard starts, injector fault codes, or uneven idle, inspecting or replacing the fuel rail should be part of your diagnostic checklist. Always verify proper torque specs and replace seals during installation to avoid leaks or pressure loss.

This component is widely supported across dealerships and diesel parts distributors and is considered essential for maintaining OEM-level functionality in the Titan XD’s fuel system.

The high pressure fuel rail is a key part of a common rail fuel injection system, delivering fuel at extremely high pressure to the injectors. If it begins to fail, the symptoms can be serious and should be addressed immediately to avoid engine damage or stalling. Below is a breakdown of how to recognize a failing fuel rail and what to do about it.

Key Symptoms of a Failing High Pressure Fuel Rail

1. Hard Starting or No Start
One of the most common signs of rail issues is difficulty starting, especially after the engine has been sitting for a while. A failing rail may not hold pressure after shutdown or may struggle to build pressure on startup.

2. Low or Unstable Fuel Pressure
Modern engines use sensors to monitor fuel rail pressure. If the rail cannot maintain the correct PSI, the ECM will detect it and may reduce injector pulse width or shut down fuel delivery entirely. This often triggers diagnostic codes like:

  • P0087 (Fuel Rail/System Pressure Too Low)
  • P0088 (Fuel Rail/System Pressure Too High)

3. Surging or Hesitation During Acceleration
If the rail isn’t delivering consistent pressure, fuel delivery to injectors can fluctuate. This leads to poor throttle response, engine hesitation, or stuttering under load.

4. Fuel Leaks or Visible Cracks
Cracks in the fuel rail, leaks at fittings, or fuel odor near the engine can indicate mechanical failure. High pressure leaks are dangerous and should be dealt with immediately.

5. Check Engine Light and DTCs
The ECM will often throw codes related to fuel pressure deviation, pressure sensor range, or injector misfire patterns when the rail isn’t functioning properly.

6. Injector Misfires or Cylinder Imbalance
A bad fuel rail can unevenly supply injectors, resulting in misfires on specific cylinders. This can also trigger balance rate issues and lead to further diagnosis of the rail or fuel pressure regulator.

How to Diagnose It

  • Read Live Data
    • Using a scan tool, monitor the actual vs. commanded fuel pressure. Inconsistencies can help pinpoint the issue.
  • Perform a Pressure Test
    • A manual gauge can be used to test pressure at the rail. Consistently low or high pressure indicates trouble.
  • Checzk the Fuel Pressure Sensor
    • Sometimes the issue lies not in the rail itself, but in the sensor giving inaccurate readings.
  • Inspect for Leaks
    • Use visual inspection and sniff tools to identify any leaking fuel from the rail, injectors, or high-pressure lines.
  • Look at Fuel Pump Output
    • A weak high-pressure pump can also cause rail issues—rule that out during testing.

Common Causes of Fuel Rail Failure

  • Internal clogging from fuel contamination or debris
  • Faulty pressure relief valve
  • Cracked rail body due to heat or vibration
  • Sensor or wiring failure on the pressure sensor
  • Worn or sticking injectors placing load on the system

While you can sometimes continue to drive short-term with minor symptoms, a failing high pressure fuel rail should be diagnosed and repaired quickly. Ignoring it can lead to injector damage, poor combustion, engine derates, or a complete no-start condition. If you're seeing pressure-related codes, fluctuating performance, or fuel leaks, it’s time for a proper diagnostic procedure and likely a replacement or repair. Let me know if you’d like help walking through code-specific steps.
