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.
"This Product Doesn't Have a Core"
Installed on Detroit DD8 engines from model years 2017–2021, OEM A9360702235 is a high-pressure fuel line designed to carry pressurized fuel between key components of the fuel system. This line is manufactured to OEM specifications to ensure proper fitment and compatibility with factory fuel system assemblies. Built from durable materials, it is engineered to handle the high-pressure demands and operating conditions common in modern diesel applications. The component supports consistent fuel flow by maintaining secure connections and proper sealing. It is a reliable option for fleet service and targeted repair needs requiring dependable fuel system operation.

The Detroit DD8 High Pressure Line 2017–2021: OEM A9360702235 is a fuel system component designed to carry high-pressure diesel fuel from the common rail to the fuel injector on Detroit DD8 engines. It is engineered specifically for model years 2017 through 2021 and built to withstand the extreme pressures generated by the high-pressure common rail system.
In a common rail diesel setup, fuel is pressurized by the high-pressure fuel pump and stored in the rail. From there, high-pressure lines like OEM A9360702235 deliver fuel directly to each injector. Because injection pressures can reach very high levels, the line must be manufactured to strict tolerances to ensure proper sealing, durability, and safety.
Key characteristics of the Detroit DD8 High Pressure Line include:
- Designed for Detroit DD8 engines (2017–2021)
- Transfers fuel from the common rail to the injector
- Built to handle high fuel pressures
- Precision-formed for proper fitment and sealing
This component plays a crucial role in maintaining consistent fuel delivery and accurate injection timing. A properly functioning high-pressure line helps support stable engine operation, controlled combustion, and overall fuel system reliability.
In summary, OEM A9360702235 is an essential part of the Detroit DD8 fuel system, ensuring safe and precise fuel transfer under high-pressure conditions.
You should replace your high pressure fuel line as soon as there are signs of leakage, damage, or pressure instability. High pressure lines operate under extreme fuel pressures, especially in common rail diesel systems, and even minor defects can lead to performance issues or serious safety risks.
Replacement becomes necessary if the line shows visible cracking, corrosion, kinks, or fuel seepage. Because these lines are designed as precision components, they should never be bent, reshaped, or reused once removed in many high-pressure systems. Even slight deformation can prevent proper sealing and lead to pressure loss.
Midway through diagnosis, the following conditions typically indicate high pressure line replacement is required:
- Visible fuel leaks or wetness around fittings
- Rail pressure codes or unstable fuel pressure readings
- Damaged threads or sealing surfaces
- Corrosion or physical damage to the line
- Line removed during injector or rail replacement (in many OEM systems)
- Evidence of vibration-related fatigue cracking
If a high pressure fuel line fails, do not attempt temporary repairs or reuse compromised components. Always torque fittings to manufacturer specifications and inspect related components such as injectors and the fuel rail for damage.
In high-pressure fuel systems, small issues can quickly escalate. Prompt replacement of damaged lines ensures proper fuel delivery, protects injectors and the high-pressure pump, and prevents dangerous fuel leaks under extreme pressure.
It’s a high-pressure fuel line designed to deliver pressurized fuel between components on Detroit DD8 engines from 2017 through 2021.
It is installed between the high-pressure fuel pump and related fuel delivery components on the engine.
It carries regulated fuel under high pressure to support correct injector supply and delivery.
Yes, it is an OEM-specified line intended for direct replacement on compatible DD8 engines.
