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.

    • By delivering the correct amount of fuel at precise pressure, the pump helps the engine run smoothly, avoiding issues like rough idling, misfires, or power loss.

  • Supports Fuel Efficiency

    • Proper fuel delivery enables the engine to burn fuel efficiently, reducing fuel consumption and operating costs over time.

  • Prevents Engine Damage

    • A malfunctioning fuel pump can cause insufficient fuel delivery, leading to poor combustion and potential engine damage. The OEM 1J500-50504 pump is designed for reliable and long-lasting performance to prevent such issues.

  • Specifically Designed for Kubota V3800 Engines

    • This high-pressure fuel pump is engineered to fit perfectly with the Kubota V3800 engine, ensuring compatibility and reliable functionality.

The Kubota V3800 High Pressure Fuel Pump (OEM 1J500-50504) plays a crucial role in maintaining consistent fuel pressure, supporting fuel efficiency, and preventing engine damage. Regular maintenance of this component can help extend your engine’s lifespan and ensure smooth operation. At TamerX Diesel Parts, we offer high-quality OEM fuel pumps to keep your Kubota V3800 engine running efficiently and reliably.

The high-pressure fuel pump is a critical component in modern vehicles, responsible for delivering fuel to the engine at precise pressures for optimal combustion and performance. Like any mechanical part, high-pressure fuel pumps have a limited lifespan, and their longevity can be influenced by several factors. In this blog, we’ll explore how long a high-pressure fuel pump typically lasts and what factors impact its durability.

Factors Affecting the Lifespan of a High-Pressure Fuel Pump:

  • Quality of Fuel

    • The quality of the fuel you use has a significant impact on the longevity of your high-pressure fuel pump. Contaminated or low-grade fuel can introduce dirt and impurities into the fuel system, which can damage the pump’s internal components over time.

  • Maintenance and Care

    •  Regular maintenance is essential for extending the life of a high-pressure fuel pump. This includes timely fuel filter replacements and consistent oil changes, which help keep the fuel system clean and prevent wear and tear on the pump.

  • Driving Conditions

    •  How and where you drive can also affect the lifespan of your fuel pump. Driving in harsh conditions, towing heavy loads, or operating the vehicle in extreme temperatures can put extra strain on the pump and lead to premature wear.

  • Normal Wear and Tear

    • Like any other engine component, high-pressure fuel pumps experience normal wear and tear as they age. Depending on usage and maintenance, they generally last between 100,000 and 150,000 miles before they begin to show signs of deterioration.

  • Early Warning Signs

    • Keeping an eye on early symptoms of a failing pump, such as difficulty starting, loss of power, or rough idling, can help you address potential issues before they escalate into more severe problems.

On average, a high-pressure fuel pump can last between 100,000 and 150,000 miles, but this depends on factors such as fuel quality, maintenance practices, and driving conditions. Regular upkeep, including timely fuel filter replacements and using clean, high-quality fuel, can significantly extend the lifespan of your fuel pump. If you notice symptoms like engine hesitation, poor fuel efficiency, or starting problems, it’s crucial to have your fuel system inspected by a professional to avoid further damage and costly repairs. Proper maintenance and attention to warning signs are key to ensuring the long-term performance of your high-pressure fuel pump.

Hard starting, rough idling, reduced power, and excessive smoke can indicate pump failure.

Air in the fuel system, worn-out bearings, or a failing pump can produce unusual noises.

Air bubbles in the fuel can reduce pressure, causing misfires and engine hesitation.

Regular fuel filter replacements, clean fuel usage, and periodic pressure checks help prolong pump lifespan.
