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 Kubota V3800 High Pressure Fuel Pump, OEM 1G421-50501, is a key component of the diesel engine's fuel system. It ensures the fuel is pressurized and delivered to the injectors, allowing for efficient combustion. This pump is designed to handle the demanding requirements of the V3800 engine, ensuring smooth operation and optimal fuel efficiency.
How It Works
The fuel pump draws fuel from the tank, pressurizing it to the necessary levels. This pressurized fuel is then sent through fuel lines to the injectors. The injectors, in turn, spray the fuel into the combustion chamber, where it mixes with air and ignites.
Key Functions of the Kubota V3800 Fuel Pump:
- Pressurizes Fuel
- Increases fuel pressure for optimal combustion.
- Regulates Flow
- Maintains a steady flow of fuel to the engine.
- Ensures Efficient Combustion
- Provides the right amount of fuel at the right pressure.
- Supports Engine Power
- By supplying fuel consistently, it supports the engine's power output.
If the fuel pump fails, the engine may experience issues such as rough idling, stalling, or a lack of power. Regular maintenance and timely replacement are crucial to keep the Kubota V3800 running smoothly.
A high-pressure fuel pump is a crucial component of your vehicle’s engine. It ensures that the fuel is delivered at the right pressure for optimal engine function. Over time, this pump can wear out, affecting the overall functioning of the engine. But how often should it be replaced?
The general recommendation for replacing a high-pressure fuel pump depends on several factors, including the vehicle's make, model, and driving habits. However, certain signs can indicate when it's time for a replacement:
- Unusual engine noises
- A loud or whining noise from the fuel tank could mean the pump is struggling.
- Difficulty starting
- If your vehicle takes longer to start, the fuel pump might be losing pressure.
- Poor fuel efficiency
- A failing pump can cause inconsistent fuel flow, leading to lower fuel efficiency.
- Check engine light
- This light could indicate several issues, including a failing fuel pump.
To maintain engine health, consider having the fuel pump inspected during regular maintenance intervals. Most high-pressure fuel pumps can last around 100,000 to 150,000 miles, but this can vary. Always consult your vehicle's manual and your mechanic for the best advice. Replacing the fuel pump at the right time can help avoid more extensive engine issues down the line.
You might hear whining, rattling, or ticking if the pump’s internals are worn.
It ensures fuel is atomized properly for cleaner and more efficient combustion.
The engine may not start or could shut down due to lack of fuel pressure.
Yes, even small particles can score internal surfaces and degrade performance.
