Bosch 0986437364 High-Pressure Common Rail Fuel Injection Pump

The Bosch 0986437364 is a high-pressure common rail fuel injection pump designed for diesel engine applications. This pump cross-references to alternate part numbers 0445010346, 0445010143, 0445010048, and 0445010078, and is commonly used in Mercedes Benz Sprinter diesel vehicles with OEM numbers A6460700401, A6110701401, A6480700001, A6460700101, and A6460700301.

Key Features:

• Three-plunger radial piston design operating at pressures of 1100-1350 bar
• Generates and sustains extremely high pressures reaching up to 26,000 PSI (1,800 bar) for precise fuel delivery
• Fuel-lubricated internal components for reliable long-term operation
• Integrated gear pump for consistent fuel supply to the high-pressure elements
• Compatible with electronic metering unit (MPROP/FCA) for precise fuel control

The metering unit, also known as the MPROP, FCA, or fuel pressure regulator, regulates the maximum flow rate the CP3 delivers to the rail. This critical component ensures optimal engine performance across all operating conditions, from idle to full load. The pump's three-plunger radial design provides smooth, consistent fuel delivery while maintaining the extreme pressures required by modern common rail diesel injection systems.

Application Note: This is typically available as a remanufactured or exchange unit. Professional installation is recommended, and verification of part number compatibility using your vehicle's VIN or original pump part number is essential before purchase.
