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.

Modern diesel engines like the Freightliner DD15 demand precise fuel delivery—especially under high load or in cold start conditions. The high-pressure fuel pump is what supplies injectors with proper fuel pressure across all operating ranges. The OEM DDERA4720902150 pump is engineered to meet those demands for Freightliner DD15 models from 2022-2025. Using the right pump helps ensure reliable start-ups, consistent power, and fewer fuel system issues down the line.

  • Delivers stable, high fuel pressure required for the injectors to atomize fuel correctly—poor fuel spray often shows up as misfires, smoke, or rough idle.

  • Helps reduce negative symptoms like hard starts, delayed acceleration, and low power output, which often stem from worn or underperforming fuel pumps.

  • Minimizes risk of leaks, pressure drop, or cavitation by using components built to OEM tolerances, ensuring that fuel supply remains constant under various pressures.

  • Protects downstream parts like the fuel rail, injectors, and emissions control modules by maintaining smooth, correct pressure flow—preventing premature wear.

  • OEM fit ensures straightforward installation and reliable alignment, which reduces downtime and avoids complications due to mismatched parts.

If your DD15 is suffering from sluggish response, start-up problems, or that creeping power loss, replacing the fuel pump with the OEM DDERA4720902150 is more than an upgrade—it’s a reset to what your fuel system was designed to deliver. Tamerx Diesel Parts offers genuine, durable replacements so your engine runs cleaner, starts easier, and holds strong between maintenance intervals.

 

A high-pressure fuel pump plays a vital role in delivering consistent and precise fuel pressure to meet the demands of modern diesel and gasoline engines. However, these components are susceptible to wear and failure if not properly cared for. By following a few key maintenance practices, you can significantly extend the lifespan of your high-pressure fuel pump and avoid costly repairs or downtime.

Maintenance Tips for High-Pressure Fuel Pump Longevity

  • Use Clean, High-Quality Fuel
    Contaminated fuel is one of the leading causes of pump failure. Always fill up from trusted fuel stations and consider using fuel additives that clean the system and prevent buildup.

  • Replace Fuel Filters Regularly
    Dirty or clogged fuel filters can restrict flow and cause the pump to work harder than it should. Stick to the manufacturer’s recommended filter change intervals—or sooner if you operate in dusty or harsh environments.

  • Inspect Fuel Lines for Leaks or Blockages
    Regularly checking for cracked hoses or debris in the fuel system can prevent pressure imbalances that may overwork the pump and lead to premature wear.

  • Avoid Running on Low Fuel
    Driving with low fuel levels can cause air pockets in the system and reduce the cooling and lubrication the pump needs, increasing wear over time.

  • Monitor Fuel Pressure
    Periodic pressure testing can help catch early signs of malfunction or restriction. This proactive step ensures the pump is operating within the proper pressure range.

  • Clean or Replace the Fuel Tank Vent
    A blocked vent can create vacuum pressure, making it harder for the pump to draw fuel. Regular maintenance of the vent helps keep fuel flow steady.

  • Schedule Professional Inspections
    Even with DIY maintenance, regular professional inspections help detect early warning signs, such as abnormal pump noise or pressure inconsistencies, before they lead to failure.


Preventive care and good fueling habits go a long way in protecting your high-pressure fuel pump. From clean filters to regular inspections, these simple maintenance steps not only extend the pump’s lifespan but also contribute to smoother engine operation and lower long-term costs. Taking action early helps you avoid breakdowns and keep your diesel system running strong.

Early signs include hard starts, inconsistent or low rail pressure, unusual noise from the pump area, or rough engine idle.

Failing pump results in insufficient fuel pressure, leading to engine misfires, loss of power, or inability to start.

Checking fuel rail pressure under load against specifications and listening for abnormal pump noises are effective checks.

Only external cleaning should be done by most operators, with internal servicing left to qualified technicians to avoid harming precise components.
