This specification features a high-pressure electronically controlled common rail fuel pump assembly for diesel engines (standard part numbers: A6650170321 / 6650170321; common OE cross-reference and interchangeable identification numbers include 28234982, 28249008, A6650700101, etc.). It is primarily matched to the D27DT / D27DTP 2.7L series inline five-cylinder high-pressure common rail diesel power platform and is widely used in rugged SUVs, multi-purpose pickup trucks, and light commercial vans).
As the core of the entire common rail fuel supply system and a key assembly for establishing pressure, it is responsible for rapidly increasing low-pressure diesel fuel to a high-pressure steady state and accurately delivering it to the common rail cavity, ensuring that each cylinder's injection actuator receives sufficient and stable pressure under different speeds and loads.
The product adheres to industrial manufacturing standards of "high-pressure steady-state establishment and micron-level precision fitting." The pump body is made of high-strength forged alloy steel, while the internal dual-plunger assembly and fuel metering valve are made of specially quenched bearing steel. The surface is coated with a low-friction, ultra-wear-resistant hardened coating, effectively preventing internal scoring and pressure leakage caused by diesel impurities. After the parts are installed, drivers and mechanics will experience a very noticeable improvement in operation: crisp and quick cold starts in the morning; stable oil pressure establishment and significantly reduced noise at low idle speeds; and a responsive and sensitive accelerator pedal during city driving, hill climbing with a full load, or highway overtaking, providing smooth acceleration and continuous power, resulting in a new-car-like light and smooth driving experience and excellent fuel efficiency.
Problems Solved: Effectively reduces intermediate procurement costs, addressing issues such as accumulated tolerances exceeding standards, slow oil pressure establishment, and high-pressure seal leakage risks inherent in traditional OEM and multi-level distribution chains.
Value Brought: Leveraging a self-operated standardized production base for precise control, eliminating intermediate markups, and ensuring highly consistent pressure and flow parameters for each high-pressure pump, this reduces maintenance budgets while providing robust and reliable power for vehicle operation.
Problems Solved: Addresses issues such as response delays, pressure relief jamming leading to engine misfires and vibrations, and wasted time and expenses due to repeated disassembly and debugging, which are common with inferior high-pressure oil pumps.
Value Brought: Each high-pressure oil pump undergoes fully automated digital testing before leaving the factory. Pressure stability and sealing response are precisely calibrated under simulated high-temperature and ultra-high-pressure conditions, ensuring immediate usability upon installation and significantly saving time and costs associated with equipment disassembly and debugging.
Problems Solved: Addresses the costly delays and lost work due to fuel system failures causing breakdowns in commercial freight and daily passenger vehicles, which are high-attendance productivity tools.
Value Brought: The warehousing center maintains ample stock of best-selling specifications year-round, enabling rapid response after order confirmation and priority packing and dispatch within 24-48 hours. This significantly shortens logistics and delivery cycles, helping fleets and owners quickly restore equipment availability and effectively avoid downtime losses.
Problems Solved: Addresses the issue of premature wear, scoring, and pressure relief jamming of internal plunger components caused by differences in diesel lubricity and sulfur content across different regions.
Value Brought: The core plunger components utilize high-strength special bearing steel and surface anti-corrosion hardening treatment, greatly improving fatigue resistance and wear resistance. Even under harsh environments and prolonged high-load operation, it maintains stable performance, avoiding the additional costs of frequent disassembly and repair.

Intercity Business Travel and Off-Road Long-Distance Driving: Diesel SUVs and off-road vehicles require extremely high stability and responsiveness from the high-pressure fuel pump during long-distance highway cruising and complex off-road conditions. When drivers notice sluggish acceleration for overtaking, weak power during high-gear uphill climbing, or slow oil pressure build-up at idle, mechanics should promptly replace the pump with this high-pressure fuel pump. After replacement, oil pressure build-up is stable and rapid, engine power output is crisp and brisk, throttle response is smooth, effectively improving driving quality and fuel efficiency.
Short-haul freight and commercial passenger/freight transport scenarios: Multi-functional pickup trucks and light passenger vehicles are frequently deployed fully loaded, requiring the engine to continuously provide stable high torque output at low speeds. When vehicles experience starting difficulties, excessive acceleration, or stalling under high load, the maintenance team promptly updates the high-pressure fuel pump assembly. A stable and powerful fuel pressure supply restores the engine's full power, easily handling frequent start-stop cycles and heavy loads, ensuring continuous and efficient transport operations.
Q: Can I install the product directly after receiving it? Is additional calibration required?
A: Each high-pressure fuel pump has undergone full-condition pressure and flow calibration before leaving the factory. Provided the fuel lines are clean, it can be directly put into use after a professional technician installs it according to the standard connector torque and removes air from the fuel system.
Q: What about the delivery time and inventory status for bulk purchases?
A: We have our own production base and large warehouse, and we maintain a large inventory of this model. Standard orders can be shipped within 24-48 hours, and large-volume orders can also be arranged for rapid factory production.
Q: What quality inspections does the product undergo before leaving the factory?
A: All oil pumps are assembled in a Class 100 cleanroom and undergo 100% high-temperature, ultra-high-pressure dynamic bench testing. The build-up pressure, return oil volume, and sealing performance are strictly monitored to ensure stable performance after installation.
Q: What is the warranty period for the product? How are quality problems handled?
A: We provide a 12-month warranty for this product. During the warranty period, in the event of performance failure caused by non-human factors, we will provide rapid replacement or after-sales technical support to protect your rights as a user.
