0445010874 Cp4 High Performance Fuel Pump for Dodge 6.7L

This electronically controlled high-pressure common-rail diesel fuel pump assembly (Part ID: 0445010874 / 0 445 010 874; interchangeable with OE references such as 0445010616, 0445010689, 0445010690, 059130755BS, and 059130755BT) is precision-engineered for 2.7 TDI and 3.0 TDI V6 diesel platforms. It is widely compatible with mid-to-large diesel sedans, SUVs, and light commercial vehicles. As the core component responsible for generating extreme rail pressure and ensuring stable fuel delivery, this pump 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 control valve spool undergo precision hardening and feature ultra-hard, wear-resistant coatings to effectively withstand 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 with reduced pump noise, and throttle responsiveness is markedly enhanced during heavy-load hill climbs or high-speed acceleration. This restores factory-standard driving dynamics and ensures excellent fuel efficiency.

Direct-from-factory manufacturing with optimized cost structures throughout the process. We provide a one-stop, high-standard parts supply solution that eliminates common points such as complex procurement, excessive intermediary markups, and inconsistent quality tolerances. Precision production on standardized assembly lines ensures highly consistent fuel pressure and flow rates across all cylinders, delivering reliable power output while keeping maintenance budgets under control.

Tested on dynamic pressure benches across all operating conditions and subjected to rigorous quality inspections. Addressing issues such as fluctuating oil pressure, sluggish acceleration, and intermittent warning lights often caused by substandard components, every high-pressure pump undergoes rigorous factory testing on automated rigs that simulate real-world high-temperature and high-pressure conditions. Precision testing of sealing integrity and fuel return rates across various pressure ranges ensures the unit is ready for immediate installation, significantly reducing labor costs associated with repeated removal, reinstallation, and troubleshooting.

Reliable large-scale warehousing and rapid shipping capabilities. To mitigate downtime losses and operational delays caused by fuel system failures in commercial and commuter vehicles, our warehouse maintains ample stock of core 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 and wear-resistant protective coatings. Designed to combat premature component wear and valve spool sticking—often caused by poor diesel lubricity or high sulfur content in certain regions—critical internal wear parts are crafted from premium special alloy bearing steel. Enhanced with specialized surface hardening treatments, these components offer superior fatigue and wear resistance, ensuring stable performance under harsh conditions and prolonged continuous operation, thereby significantly extending service life.

Daily urban commuting for luxury diesel sedans and SUVs: Vehicles equipped with large-displacement V6 diesel engines require rapid pressure build-up and stable idling performance during frequent stop-and-go city driving. This high-pressure fuel pump is the ideal replacement when vehicles exhibit slow starting, sluggish low-speed acceleration, or unstable idle fuel pressure. Installation ensures smooth and rapid pressure build-up and responsive throttle action, enhancing overall driving comfort. Long-distance, cross-province highway cruising and heavy-load towing: When multi-purpose diesel SUVs and commercial vehicles travel long distances at high speeds or tow heavy loads, their engines operate under sustained high-load conditions for extended periods. If a vehicle experiences power loss while climbing in a high gear or stalls under heavy load, installing this high-specification high-pressure fuel pump restores robust power delivery, ensuring efficient and smooth long-distance travel.

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 unit can be put into service immediately after installation by a professional technician using standard torque specifications and proper air-purging procedures.

Q: What are the 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 rapidly arranged.

Q: What quality inspections 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.

Q: What is the warranty period for the product?

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