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"
Developed to provide precise monitoring of high-pressure fuel conditions, the OEM 7210-0521 Fuel Rail Pressure Sensor fits Detroit DD5 and DD8 engines produced from 2018 to 2024. This sensor transmits critical data to the engine control module, helping maintain proper fueling adjustments and steady system behavior under varying demands. Its OEM-grade construction ensures accurate fitment, stable signal clarity, and durability against heat, vibration, and pressure fluctuations. When symptoms such as inconsistent readings, starting difficulties, or pressure-related diagnostic codes occur, this sensor offers a dependable replacement option. Built with durable materials and precise engineering, it supports reliable operation across all compatible DD5 and DD8 applications within this model range.

The Detroit DD5 and DD8 Fuel Rail Pressure Sensor (OEM 7210-0521) is a key engine management component that measures the high-pressure fuel inside the common rail system. This data is essential for the engine control module, which uses the information to regulate fuel delivery with precision.
What the Sensor Does
The sensor continuously monitors fuel pressure inside the rail and converts that pressure into an electrical signal. The engine control module reads this signal and adjusts injector timing and fuel quantity in real time. This ensures the engine runs smoothly, delivers consistent power, and maintains clean combustion.
Why This Sensor Is Important
- Maintains correct fuel pressure for stable operation
- Ensures accurate injector function by providing real-time pressure data
- Supports clean combustion by optimizing fuel delivery
- Protects the high-pressure system from dangerous spikes or drops
- Prevents drivability issues such as hard starting or hesitation
A failing fuel rail pressure sensor can cause rough running, loss of power, increased emissions, poor acceleration, or engine derate conditions. Fault codes may appear when the sensor sends incorrect or inconsistent readings. Using the correct OEM 7210-0521 part helps ensure reliable performance and long-term durability in DD5 and DD8 engines.
Driving with a failing fuel rail pressure sensor is not recommended. This sensor sends critical data to the engine control system, helping it regulate fuel delivery accurately. When it starts to malfunction, the engine may struggle to maintain consistent fuel pressure, leading to irregular behavior and potential safety concerns.
At first, the symptoms may seem minor, but continuing to drive without diagnosis can lead to unexpected breakdowns or further damage to fuel system components.
Risks of driving with a failing fuel rail pressure sensor include:
- Hard starting or long crank times
- Rough idle due to unstable fuel pressure
- Sudden stalling, especially at low speeds
- Check Engine Light tied to fuel pressure faults
- Increased fuel consumption from incorrect readings
In severe cases, the engine may fail to start altogether or may run unpredictably, creating unsafe conditions on the road.
If you notice warning signs such as rough running, fluctuating fuel pressure readings, or fault codes, schedule diagnostics as soon as possible. Replacing the faulty sensor promptly helps restore accurate fuel control and prevents unnecessary strain on other components.
It monitors high-pressure fuel levels inside the common rail so the ECM can precisely control injector operation.
Hard starting, hesitation, or rail-pressure-related diagnostic codes may appear.
It adjusts injection timing, fuel quantity, and protection strategies based on real-time rail pressure feedback.
Yes, debris or metal shavings can obstruct the sensor port and produce inaccurate readings.
