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 Bobcat and Doosan D34 engines from model years 2013–2017, OEM 7450707 is a fuel rail pressure sensor designed to monitor pressure within the high-pressure fuel system. This sensor is manufactured to OEM specifications for accurate fitment and compatibility with factory engine management systems. Constructed from durable materials, it is built to withstand the operating conditions common in modern diesel applications. The component supports precise pressure feedback to the engine control unit to help maintain stable fuel delivery and system operation. It is a reliable option for fleet maintenance and targeted repair needs requiring dependable fuel system pressure monitoring.

The Bobcat / Doosan D34 Fuel Rail Pressure Sensor 2013–2017: OEM 7450707 works by continuously measuring the fuel pressure inside the common rail and sending that information to the engine control module (ECM). This data allows the engine’s fuel system to maintain precise pressure levels required for accurate fuel injection.
In a common rail diesel system, fuel is pressurized by the high-pressure pump and stored in the fuel rail before being delivered to the injectors. The pressure sensor is mounted directly on or near the rail, where it monitors real-time pressure conditions.
Here’s how the sensor operates:
- It detects fuel pressure using an internal sensing element (typically a strain gauge or piezoresistive element).
- The pressure reading is converted into an electrical voltage signal.
- That signal is transmitted to the ECM.
- The ECM adjusts the fuel control actuator or pump output to maintain the desired pressure level.
By constantly monitoring rail pressure, OEM 7450707 helps ensure the injectors receive fuel at the correct pressure for proper atomization and combustion. If pressure is too high or too low, the ECM can make rapid corrections to prevent drivability issues.
A properly functioning fuel rail pressure sensor supports smooth engine operation, stable idle, controlled emissions, and overall fuel system reliability in Bobcat and Doosan D34 engines produced between 2013 and 2017.
Prolonging the lifespan of your fuel rail pressure sensor starts with protecting the fuel system from contamination and preventing excessive pressure fluctuations. The sensor is designed to monitor high-pressure fuel conditions accurately, but it relies on clean fuel, stable pressure, and proper electrical connections to function correctly.
The most important factor is maintaining clean, properly filtered fuel. Dirt, water, or metal particles from a failing high-pressure pump can damage the sensor diaphragm or clog its port. Replacing fuel filters on schedule and draining water separators regularly helps prevent contamination-related sensor failure.
Midway through routine maintenance, focus on these best practices:
- Replace fuel filters at recommended intervals
- Use high-quality diesel fuel from reputable sources
- Avoid running the fuel tank extremely low
- Address injector imbalance or over-fueling issues promptly
- Repair high-pressure pump problems immediately
- Inspect wiring harnesses and connectors for corrosion or damage
Stable system voltage and secure electrical connections are also critical. Voltage spikes, poor grounds, or damaged connectors can cause inaccurate readings or premature failure.
In most cases, the fuel rail pressure sensor does not fail on its own. It is often damaged by upstream fuel contamination, pressure instability, or electrical issues. Consistent fuel system maintenance, prompt repair of pump or injector faults, and regular inspections are the most effective ways to extend sensor lifespan and ensure accurate fuel pressure control.
It measures the real-time pressure within the fuel rail and sends that data to the engine control module.
Yes, a malfunctioning sensor can cause diagnostic trouble codes related to fuel pressure readings.
Yes, it communicates with the engine control module to help regulate fuel delivery.
Yes, it is an OEM-specified sensor intended for direct replacement on compatible engines.
