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.

In Detroit DD13 engines, the high pressure fuel rail plays a critical role in maintaining accurate fuel delivery to each injector. When this part begins to fail, it can cause inconsistent engine operation, reduced efficiency, and possible engine warning lights. The OEM A4710780745 High Pressure Fuel Rail, designed for 2016–2021 DD13 models, is a direct-fit solution for restoring proper fuel system function.

Key Signs of Fuel Rail Problems in DD13 Engines:

  • Engine Starting Trouble – Poor fuel pressure may cause long cranks or failure to start.

  • Fuel Odor or Visible Leaks – Leaks from the rail or fittings may indicate damage or cracks.

  • Check Engine Light Activation – Diagnostic codes often point to fuel pressure irregularities.

  • Irregular Engine Idle or Misfires – Uneven fuel delivery impacts smooth engine operation.

  • Drop in Fuel Efficiency – Faulty pressure regulation can lead to wasted fuel and poor mileage.

Benefits of Using OEM A4710780745 from Drive On Diesel:

  • Engineered for precise fitment in Detroit DD13 engines (2016–2021)

  • Delivers consistent high-pressure fuel to each injector

  • Promotes stable engine idle and combustion quality

  • Built to OEM reliability standards for long-term use

  • Backed by trusted quality from Drive On Diesel Diesel Parts

If your DD13 engine is showing signs of inconsistent fuel delivery or warning lights, it may be time to inspect the high pressure fuel rail. Replacing it with the OEM A4710780745 unit can restore proper fuel flow and prevent further engine issues. Drive On Diesel Diesel Parts offers dependable OEM replacements to keep your engine running reliably.

The high-pressure fuel rail is a vital part of your engine’s fuel injection system, responsible for maintaining consistent pressure and delivering fuel to the injectors. When it malfunctions, it can lead to engine misfires, hard starting, poor fuel economy, or even stalling. Understanding the common causes of high-pressure fuel rail failure can help prevent costly repairs and maintain reliable engine performance.

Common Causes of High-Pressure Fuel Rail Malfunctions:

  • Fuel Contamination – Dirt, debris, or water in the fuel can clog injectors or pressure sensors, disrupting fuel flow and accuracy.

  • Faulty Fuel Pressure Sensor – A failing sensor can send incorrect signals to the ECU, leading to improper fuel delivery and pressure regulation.

  • Leaking or Cracked Rail – Physical damage to the rail can cause pressure loss and uneven fuel distribution across the injectors.

  • Weak or Failing High-Pressure Fuel Pump – If the pump can’t maintain the required pressure, the fuel rail won’t operate effectively.

  • Injector Leaks – A leaking injector can cause pressure drop within the rail, leading to performance issues and rough engine operation.

  • Electrical Problems – Damaged wiring or poor connections to sensors or the pump can interfere with fuel pressure control.

  • Extreme Heat or Vibration – Over time, exposure to excessive heat or engine vibration can lead to fatigue and failure in components attached to the fuel rail.

A malfunctioning high-pressure fuel rail can quickly lead to engine performance issues and long-term damage if left unaddressed. Regular maintenance, using clean fuel, and responding to early warning signs—like a check engine light or poor acceleration—can help prevent fuel rail problems and keep your engine running smoothly.

External cleaning is safe, but internal cleaning is not advised due to precision tolerances.
