New High-Quality Fuel Injection Pump 0445010138 0445010203 0445010092 for Opel Suzuki Z13dt Y13dt

This high-pressure common-rail diesel fuel pump assembly (Part ID: 0445010138 / 0 445 010 138; common OE cross-references include 0445010079, 0986437318, 6460700101, A6460700101, etc.) is precision-engineered for the OM646/OM647 series 2.2 CDI diesel engine platform. It is widely fitted across various passenger cars and commercial vehicles, including the C-Class, E-Class, Sprinter, Vito, and Viano. Serving as the core power source for generating fuel pressure and regulating flow within the fuel supply system, it is responsible for rapidly pressurizing low-pressure diesel and delivering it stably to the high-pressure rail, ensuring a consistent and ample fuel supply across all engine speeds.

Designed and manufactured to standards emphasizing "micro-precision fitment and stable ultra-high-pressure output," the pump body utilizes high-strength forged alloy steel. Internal plunger assemblies and control valve spools are crafted from premium aerospace-grade hardened bearing steel, featuring a dense, ultra-wear-resistant coating that effectively prevents internal scoring and pressure loss caused by fuel impurities. Upon installation, drivers and technicians will notice immediate improvements: crisp, rapid cold starts; reduced pump noise during low-speed idling; and steady, smooth engine operation. Whether during rapid acceleration for overtaking, steep hill climbs, or long-distance highway cruising, the throttle response is sharp and robust, delivering linear power without lag, resulting in satisfying fuel efficiency and a smooth driving experience.

• Cost-Effective Solution: Effectively reduces procurement expenses by eliminating intermediary markups associated with distribution channels—which often lead to tolerance stack-up issues, uneven fuel delivery pressure across cylinders, and high-pressure leakage risks. Leveraging standardized production bases for end-to-end precision control ensures highly consistent fuel pressure and flow rates across all cylinders, providing reliable power for vehicle operation while simultaneously cutting maintenance budgets.
• Rigorous Quality Control: Undergoes strict quality inspections on ultra-high-pressure digital dynamic test benches to address common issues found in low-quality parts—such as response lag, pressure-release valve sticking (causing engine misfires and vibration), and the wasted time and money associated with repeated disassembly and adjustment. Each pump assembly is tested on automated rigs before leaving the factory, with flow rates and sealing performance precisely calibrated under simulated real-world conditions of high temperature and ultra-high pressure. This ensures "ready-to-install" capability, drastically saving time and costs related to equipment installation and tuning.
• Rapid Response & Stock Availability: Designed for vehicles used in daily commuting and commercial transport—high-utilization assets where fuel system failures can lead to costly downtime, contract penalties, and lost productivity. Our warehousing centers maintain ample stock of popular specifications year-round; orders are prioritized for packing and dispatch within 24–48 hours of confirmation. This significantly shortens logistics cycles, helping fleets and owners quickly get their vehicles back on the road and avoiding losses caused by operational downtime.
• Specialized Quenched Alloy Plungers & Wear-Resistant Coatings: Engineered to combat premature wear and valve sticking caused by regional variations in diesel lubricity and sulfur content. Core valve components utilize high-strength specialty bearing steel and undergo surface hardening and anti-corrosion treatments. This greatly enhances fatigue and wear resistance, ensuring stable performance even under harsh environments and prolonged, high-load operation, thereby avoiding the extra expenses associated with frequent disassembly and repairs.

High-frequency long-haul transport for commercial vans and logistics vehicles: Light commercial vans frequently operate in intercity logistics and business delivery roles, often running at full load and cruising over long distances. When vehicles exhibit sluggish starting, slow fuel pressure buildup at idle, or stalling under high load, mechanics can promptly replace the high-pressure fuel pump. Following replacement, the high-pressure rail maintains stable and ample pressure, the engine regains quiet and smooth operation, and intercity transport efficiency is effectively ensured.

Diesel passenger cars—daily city commuting and highway cruising: In stop-and-go city traffic requiring frequent starts, diesel cars place high demands on the high-pressure pump regarding the speed of oil pressure buildup and idle stability. If owners notice delayed starting, sluggish low-speed acceleration, or slow oil pressure buildup, maintenance personnel should promptly replace the unit with this high-pressure fuel pump. After installation, oil pressure builds up smoothly and rapidly, and throttle response becomes crisp and agile, effectively enhancing driving quality and fuel efficiency.

Q: Can the product be installed immediately upon receipt? Is additional calibration required?

A: Each high-pressure fuel pump undergoes full-range pressure and flow calibration before leaving the factory. Provided the fuel lines are clean, professional technicians can install the unit—adhering to standard torque specifications for connections and bleeding air from the fuel system—and put it directly into service.

Q: What are the shipping lead times and stock availability for bulk orders?

A: We operate our own production facilities and large-scale warehouses, maintaining substantial stock of this model. Standard orders can ship within 24–48 hours, and we can arrange rapid production scheduling for large-volume orders.

Q: What quality inspections does the product undergo before leaving the factory?

A: All fuel pumps are assembled in Class 100 cleanrooms and undergo 100% dynamic bench testing at high temperatures and ultra-high pressures. We strictly monitor pressure buildup, fuel return volume, and sealing performance to ensure stable on-vehicle performance.

Q: What is the warranty period, and how are quality issues handled?

A: We offer a 12-month warranty on this product. Should performance failures occur due to non-human factors during the warranty period, we provide rapid replacement or technical support to safeguard your interests.
