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.

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 for delivering the precise amount of fuel to the engine’s combustion chamber. When fuel injectors malfunction, they can cause a range of issues, including low fuel pressure. Understanding how bad fuel injectors can lead to low fuel pressure can help you diagnose and fix the problem, ensuring your engine runs smoothly.

How Bad Fuel Injectors Can Cause Low Fuel Pressure

Bad fuel injectors can disrupt the fuel system in several ways, leading to low fuel pressure. Here are some common scenarios:

  • Clogged Injectors
    •  Deposits and debris can clog fuel injectors, restricting the flow of fuel into the engine. This can result in lower than normal fuel pressure, as the fuel system struggles to maintain the required pressure levels.
  • Leaking Injectors
    •  If fuel injectors are leaking, they can cause a drop in fuel pressure. Leaks allow fuel to escape before reaching the combustion chamber, reducing the overall pressure in the fuel system.
  • Faulty Injector Seals
    •  Worn or damaged seals on the fuel injectors can lead to fuel leaks, which in turn lower the fuel pressure. These seals are crucial for maintaining the integrity of the fuel system.
  • Electrical Issues
    • Fuel injectors rely on electrical signals to operate correctly. Electrical problems, such as faulty wiring or connectors, can prevent injectors from opening or closing properly, leading to inconsistent fuel pressure.
  • Injector Wear and Tear
    •  Over time, the internal components of fuel injectors can wear out, leading to inefficient fuel delivery. This wear and tear can cause fluctuations in fuel pressure as the injectors fail to maintain the necessary flow rate.

Symptoms of Low Fuel Pressure Due to Bad Injectors

Recognizing the symptoms of low fuel pressure caused by bad injectors can help you address the issue promptly. Look out for these signs:

  • Engine Misfires
    • Inconsistent fuel delivery can cause the engine to misfire, resulting in rough idling and reduced power.
  • Poor Fuel Economy
    •  Low fuel pressure can lead to inefficient combustion, causing increased fuel consumption and reduced fuel economy.
  • Hard Starting
    •  Difficulty starting the engine, particularly in cold conditions, can be a sign of low fuel pressure.
  • Loss of Power
    •  A noticeable decrease in engine power and performance, especially during acceleration, can indicate low fuel pressure.
  • Check Engine Light
    •  The check engine light may illuminate due to issues with the fuel pressure system. Diagnostic trouble codes can help pinpoint the exact problem.
  • Stalling
    •  Intermittent stalling or a complete inability to start can be signs of low fuel pressure caused by bad injectors.
