Product Description
Product Introduction: A gear-driven high-pressure common rail pump with a cast-iron housing and precision-machined internal components. It features a gear-driven input shaft, a pressure control valve, and a high-pressure outlet. The pump undergoes precision calibration to maintain stable fuel pressure across varying engine speeds.
Product Function: Draws fuel from the fuel tank and compresses it to ultra-high pressures (up to 2500 bar) for delivery to the common rail system. It works with the ECU to maintain precise fuel pressure, ensuring the injectors receive a consistent supply of high-pressure fuel for optimal combustion, power output, and emission control.
Engineered to meet the demanding fuel delivery requirements of Cummins ISG series engines, the Mettlead 4327066 High-Pressure Oil Pump (Common Rail Fuel Pump) delivers consistent, precision-controlled fuel pressure across the full operating range. Built with a robust cast-iron housing and precision-machined internal components, this gear-driven common rail pump ensures reliable performance in heavy-duty trucking, construction, and industrial applications. Whether you are sourcing for fleet maintenance or aftermarket distribution, Mettlead offers competitive pricing, fast lead times, and strict quality control on every unit shipped.
Key Features and Benefits of the 4327066 Common Rail Fuel Pump
Precision Fuel Pressure Control
Each Mettlead high-pressure oil pump undergoes precision calibration before leaving the factory. The integrated pressure control valve maintains stable fuel rail pressure across varying engine speeds and load conditions, reducing emissions and optimizing combustion efficiency in Cummins ISG diesel engines.
Gear-Driven Reliability
The gear-driven input shaft design eliminates belt-related failures and delivers consistent rotational torque directly from the engine timing gear train. This translates to longer service life and reduced unplanned downtime for fleet operators.
Heavy-Duty Cast-Iron Construction
The pump housing is manufactured from high-grade cast iron, engineered to withstand extreme pressures and thermal cycling typical of long-haul and heavy-load diesel applications. Internal components are precision-machined to OEM-level tolerances.
Direct OEM Cross-Reference
Part number 4327066 is a direct replacement for the original Cummins ISG series common rail fuel pump. Drop-in fitment eliminates modification costs and reduces installation time for workshops and fleet service centers.
