SHIPPING POLICY

Drive On Diesel 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 Drive On Diesel 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.

Drive On Diesel 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 Drive On Diesel, 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). Drive On Diesel 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 Drive On Diesel, 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. Drive On Diesel 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 Drive On Diesel core charge presented to you online today with your item is representative of the most common core charge.

The Cummins ISB 6.7L and QSB engines rely on precision fuel injectors, such as OEM 5263314, to ensure efficient combustion. These injectors are crucial for delivering fuel at the right pressure and timing, making them essential for the engine's proper functioning.

A Cummins ISB 6.7L, QSB Fuel Injector consists of several key components:

  • Nozzle
    • The part that sprays fuel directly into the combustion chamber in a fine mist for better fuel burn.
  • Solenoid
    • This controls the injector's opening and closing, regulating fuel flow based on engine needs.
  • Injector Body
    • Houses the internal components and provides the structure for the fuel injector.
  • Needle Valve
    • Controls fuel delivery, ensuring precise fuel metering for optimal efficiency.
  • Connector
    • Links the injector to the engine's control system, receiving signals that adjust fuel delivery.
  • Seals and O-rings
    • Maintain a tight seal to prevent fuel leaks and ensure proper pressure within the injector.

Each of these components works together to ensure your Cummins ISB 6.7L or QSB engine operates smoothly. If you’re noticing engine issues, it might be time to check your fuel injectors for wear or damage. Replacing faulty components can help restore proper fuel delivery and improve engine health.

Fuel injectors play a crucial role in delivering fuel to your engine. Over time, wear and tear can affect their functionality, leading to problems like poor fuel efficiency and rough idling. Knowing when to replace your fuel injectors is key to keeping your engine running smoothly.

On average, fuel injectors should be inspected every 100,000 miles, but replacement may be necessary sooner depending on driving conditions and fuel quality. Some signs that your fuel injectors need attention include:

  • Engine misfires
  • Poor fuel efficiency
  • Hard starts or no starts
  • Rough idling
  • Fuel leaks

To extend the life of your injectors, regular maintenance is important. Keeping your fuel system clean and using high-quality fuel can help avoid premature wear.

Replacing fuel injectors before they fail completely can prevent further engine damage and costly repairs. It’s always a good idea to consult your vehicle’s manual for manufacturer-recommended maintenance intervals or speak with a trusted technician.

Symptoms include hard starting, increased exhaust smoke, engine knocking, or cylinder misfires.
