BOSCH 1465ZS0050 

Fuel Quantity Control Valve (Common Rail System) 

Technical Data

Product Information

The Fuel Quantity Control Valve (also known as a Fuel Metering Valve, ZME, or MPROP) is a crucial component of the modern Common Rail diesel injection system. Located on the low-pressure side of the high-pressure pump, this electromechanical valve regulates the exact volume of fuel allowed into the high-pressure element . By compressing only the fuel that the engine actually needs, it significantly reduces the power drawn by the high-pressure pump, lowers fuel temperatures, and improves overall vehicle efficiency . This genuine BOSCH valve comes complete with necessary attachment and mounting materials, directly replacing older part number 0928400625. It is designed for specific MAN and Volvo vehicles, as well as multiple BOSCH radial piston and banked-piston pumps .

⚠ Diagnostic & Installation Tip ⚠

Before replacing the fuel quantity control valve:

• Always strictly depressurize the common rail system before performing any work. Even the low-pressure side can hold residual fuel pressure .
• Absolute cleanliness is mandatory. Even microscopic dirt particles entering the high-pressure pump during valve installation can cause catastrophic failure to the pump and injectors .
• Inspect the wiring harness connector for signs of corrosion or poor contact, as electrical issues frequently mimic mechanical valve failures .
