0445010859 0445010860 Cp4 High Performance Fuel Pump LC3z9a543A LC3q9b395AA for Ford Powerstroke 6.7L

This high-pressure diesel common-rail fuel pump assembly (Part ID: 0445010859 / 0 445 010 859; common OE cross-references include 0445010684, 0445010697, 0445010820, 0445010821, 0445010828, 0445010892, LR079958, FE93-9B395-AA, etc.) is precision-engineered. Designed for 3.0 TD/SDV6/TDV6 diesel powertrains, it is widely fitted in luxury diesel SUVs and executive sedans such as the Discovery 4/5, Range Rover IV, Range Rover Sport II, Range Rover Velar, F-Pace, XF, and XJ 3.0D. As the core power source for generating extreme rail pressure and ensuring stable fuel delivery, it efficiently pressurizes low-pressure diesel and delivers it evenly to the high-pressure fuel rail, guaranteeing a continuous and steady fuel supply across all engine speeds and operating conditions.

The pump body is constructed from high-strength forged alloy, while the core plunger and regulating valve spool undergo precision hardening and ultra-hard, wear-resistant coating treatments to effectively resist impurity erosion and internal pressure loss. Upon installation, users will notice a significant improvement in power delivery: cold starts are quick and smooth, idle operation is stable, and pump noise is reduced. During heavy-load hill climbs or high-speed acceleration, throttle responsiveness is markedly enhanced, providing agile and abundant power, thereby restoring factory-standard driving dynamics and excellent fuel efficiency.

• Direct-from-factory manufacturing with cost optimization throughout the entire process. We provide a one-stop, high-standard parts supply solution, effectively addressing common challenges such as cumbersome procurement workflows, excessive intermediary markups, and inconsistent quality tolerances. Precision manufacturing via standardized assembly lines ensures highly consistent oil supply pressure and flow rates across all cylinders, delivering reliable power output while keeping maintenance budgets under control.
• Dynamic pressure testing across all operating conditions and rigorous quality inspections. To address issues such as oil pressure fluctuations, sluggish acceleration, and intermittent warning lights often caused by inconsistent component quality, every high-pressure pump undergoes automated bench testing simulating real-world high-temperature and high-pressure conditions. Precise testing of sealing integrity and fuel return volume across various pressure ranges ensures the unit is ready for immediate installation, significantly reducing the time and cost associated with assembly and adjustment.
• Large-scale, consistent inventory and rapid shipping capabilities. To mitigate downtime losses and operational delays caused by fuel system failures in commercial and commuter vehicles, our distribution centers maintain ample stock of key specifications. Orders are quickly processed and shipped within 24–48 hours, effectively shortening wait times and helping fleets and vehicle owners get back on the road quickly.
• High-hardness, corrosion-resistant valve components with wear-resistant coatings. Designed to combat premature wear and valve sticking caused by poor diesel lubricity or high sulfur content in certain regions, critical internal wear components are crafted from premium special alloy bearing steel. Enhanced with specialized surface hardening treatments, these parts offer superior fatigue and wear resistance, maintaining stability under harsh conditions and prolonged continuous operation, thereby significantly extending service life.

• Daily urban commuting for luxury diesel SUVs and mid-to-large sedans: Luxury SUVs equipped with the 3.0 SDV6 diesel engine demand rapid pressure build-up and stable idling performance during frequent stop-and-go city driving. Technicians install this high-pressure fuel pump to resolve issues such as slow starting, sluggish low-speed acceleration, or unstable idle fuel pressure. Post-installation, fuel pressure builds smoothly and rapidly, throttle response becomes crisp, and overall driving comfort is enhanced.
• Long-distance, cross-province highway cruising and off-road towing scenarios: When luxury diesel off-road vehicles travel long distances at high speeds or tow heavy RVs/trailers, their engines operate under sustained high loads for extended periods. If the vehicle experiences a lack of power when climbing in high gears or stalls under heavy load, the maintenance team can install this high-specification high-pressure fuel pump; its robust high-pressure fuel delivery restores the engine's abundant power, ensuring an efficient and smooth long-distance journey.

1. Q: Can the fuel pump be installed and used immediately upon receipt? Is recalibration required?

   A: Pressure and flow rate testing and calibration across all operating conditions are completed before the product leaves the factory. Provided the fuel lines are clean, the pump can be put into immediate use after being installed by a professional technician using standard torque specifications and having air bled from the fuel system.

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

   A: We operate our own production facilities and warehousing centers, maintaining a steady stock of this model year-round. Standard orders ship within 24–48 hours of confirmation, while production schedules for bulk orders can be arranged quickly.

3. Q: What quality tests does the product undergo before leaving the factory?

   A: All products are assembled in a Class 100 cleanroom environment and undergo 100% dynamic bench testing at high temperatures and ultra-high pressures. We rigorously monitor pressure build-up, fuel return volume, and sealing performance to ensure the product meets quality standards for vehicle installation.

4. Q: What is the warranty period for the product?

   A: We provide a 12-month warranty for this product. Should any malfunction occur due to non-human factors during the warranty period, we will provide rapid after-sales technical support and service to protect your interests.
