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.

Key Components of the High Pressure Fuel Pump

The John Deere QSX15 High Pressure Fuel Pump is composed of several critical parts that work together to maintain the fuel system's integrity:

  • Pump Housing
    • The exterior casing that protects the internal components from contaminants and damage.
  • Plunger and Barrel
    • These parts work in tandem to create the necessary pressure for fuel injection.
  • Delivery Valve
    • Regulates the fuel flow from the pump to the injectors, ensuring precise delivery.
  • Camshaft
    • Drives the pump's plunger, synchronizing with the engine's operation to maintain consistent pressure.
  • Seals and Gaskets
    • Prevent fuel leaks and maintain the pump's internal pressure.

Maintenance Tips

To keep your John Deere QSX15 High Pressure Fuel Pump in optimal condition, regular maintenance is crucial. Here are some tips:

  • Regular Inspections
    • Check for any signs of wear or damage to the pump and its components.
  • Clean Fuel
    • Use high-quality diesel to prevent contamination and buildup within the pump.

A high pressure fuel pump is essential for delivering fuel to the engine at the correct pressure. When it starts to fail, your vehicle can exhibit several noticeable symptoms that shouldn't be ignored.

  • Engine Misfires and Stalling
    • One of the most common signs of a failing high pressure fuel pump is engine misfires. This happens when the fuel supply is inconsistent, causing the engine to sputter. Stalling, especially at high speeds, can also indicate a problem with the pump.
  • Poor Fuel Efficiency
    • A decrease in fuel efficiency is another symptom. If your vehicle starts consuming more fuel than usual without any change in your driving habits, the high pressure fuel pump might be the culprit.
  • Strange Noises
    • Unusual noises from the fuel tank, such as whining or sputtering sounds, often signal a bad fuel pump. These sounds typically become more noticeable as the pump struggles to maintain proper fuel pressure.
  • Difficulty Starting
    • If your vehicle has trouble starting or takes longer than usual to turn over, the high pressure fuel pump could be failing. This is because the pump is unable to provide the engine with enough fuel to start efficiently.
  • Check Engine Light
    • A failing fuel pump can trigger the check engine light. While this warning light can indicate various issues, it is wise to have a diagnostic check to determine if the fuel pump is the cause.
  • Warning Signs
    • Engine misfires
    • Stalling at high speeds
    • Decreased fuel efficiency
    • Whining noises from the fuel tank

If you notice any of these signs, it’s crucial to address the issue promptly. T Don't let a failing fuel pump cause further damage to your engine.

While experienced individuals may perform the installation, professional installation is recommended to ensure proper fitment and function.

Indicators of a failing fuel pump include engine misfires, stalling, decreased fuel efficiency, unusual noises from the fuel tank, difficulty starting, and the check engine light turning on. ​

Common causes include fuel contamination, inadequate lubrication, and wear of internal components such as the plunger and barrel. ​

To test the fuel pump, connect a fuel pressure gauge to the pump outlet and observe the pressure reading while the engine is running; consult the manufacturer's manual for specific pressure specifications. ​
