0101 104 Manual Feed Pump — MERCEDES BENZ

The manual feed pump serves a critical function in the fuel delivery system of heavy-duty engines, facilitating the consistent movement of fuel to ensure stable combustion and engine performance. This component is manufactured using heavy-duty grade materials to withstand the rigorous pressure and environmental demands of the fuel system. Its robust construction ensures long-term reliability under demanding operating conditions.

This specific model is the OE-equivalent of the BOSCH 0 440 008 989 manual feed pump used in MERCEDES BENZ, MAN, and DAF heavy commercial vehicles. It provides seamless integration with various systems, including LASO (20580709) and several MAN engine configurations such as 51.12101-7097 and N1.01401-2687. By maintaining precise mechanical movement, it helps prevent fuel starvation issues during transit.

Workshop technicians should ensure that all seals and connection points are inspected during installation to maintain system integrity. This part is designed for direct replacement in compatible fuel systems, requiring standard assembly procedures for heavy commercial vehicle maintenance. Regular checks of the manual pump's responsiveness can prevent broader fuel delivery interruptions during scheduled service intervals.

Proper selection of this component ensures that the fuel flow remains uninterrupted, supporting the overall health of the engine's fuel circuit. It is an essential part for maintaining the operational efficiency of heavy trucks and buses in professional transport fleets.
