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.

Fuel injectors are critical components of your vehicle’s engine, ensuring proper fuel delivery for efficient combustion. When they malfunction, it can lead to a variety of performance issues. Diagnosing fuel injector problems promptly is essential to maintaining engine health and avoiding costly repairs. By identifying the signs and using diagnostic techniques, you can determine if your injectors are the source of the problem.

Steps to Diagnose Fuel Injector Problems

  • Observe Engine Performance
    •  Look for symptoms such as rough idling, misfires, reduced fuel efficiency, or poor acceleration, which may indicate injector issues.
  • Check for Warning Lights
    • A bad fuel injector can trigger the check engine light. Use a diagnostic scanner to retrieve error codes that may pinpoint injector-related problems.
  • Inspect for Leaks
    • Examine the injectors and surrounding areas for visible signs of fuel leaks. Damaged seals or cracks in the injector body can cause leaks.
  • Perform a Fuel Pressure Test
    • Use a fuel pressure gauge to measure the pressure in the fuel system. Low or fluctuating pressure may indicate a clogged or malfunctioning injector.
  • Listen for Clicking Sounds
    •  A functioning fuel injector typically produces a faint clicking noise. If no sound is heard, the injector may be stuck or not receiving electrical signals.
  • Conduct a Cylinder Balance Test
    • Disable one injector at a time while monitoring engine performance. A significant drop in performance indicates the injector is working; minimal change suggests a problem.
  • Inspect Spray Patterns
    • Remove the injectors and test their spray patterns. A proper injector should produce a fine mist. Irregular or weak sprays may indicate clogs or damage.
  • Test Electrical Connections
    • Use a multimeter to check for proper voltage and continuity in the injector’s electrical connections. Faulty wiring or connectors can prevent the injector from operating correctly.
  • Check for Contaminants
    • Inspect the fuel system for dirt, debris, or water contamination, which can clog or damage the injectors.

Regular Maintenance to Prevent Problems

Regular fuel system maintenance, such as replacing fuel filters and using fuel additives, can prevent many injector issues. Periodic inspections can help catch problems early, saving you from more extensive repairs.

Diagnosing fuel injector problems requires a combination of observation, testing, and inspection. By identifying issues early and taking action, you can ensure your engine operates efficiently and reliably. Regular maintenance and attention to performance indicators are essential to keeping your fuel system in top condition. Don’t ignore the warning signs—diagnose and address fuel injector problems promptly to maintain your vehicle’s performance and longevity.
