Bosch original Truck Engine Fuel Pump A0280749102 Unit Pump for OM924/925 OM926 Replacement for OEM 0414799017 A0290742302 Auto Parts original new injector

Engineered specifically for the Mercedes-Benz medium- and heavy-duty engine family, this Genuine Bosch 799 Series unit pump injector is calibrated to the precise injection parameters of the OM904, OM906, OM924, OM925, and OM926 platforms, including the intercooled LA variants. Each unit is manufactured to Bosch factory specification, ensuring exact dimensional, hydraulic, and electronic compatibility with the Unit Pump System (UPS) used across the Atego, Axor, Accelo, Citaro, Tourino, Unimog, and Zetros model lines.

The injector delivers highly accurate fuel metering at every engine speed, supporting the engine management requirements of Euro 3, Euro 4, and Euro 5 emissions standards. Precision-machined nozzles and hardened plunger components provide stable injection quantity, consistent spray pattern, and balanced cylinder delivery, which together improve cold-start behavior, enhance torque output, and reduce fuel consumption. The unit pump design eliminates the high-pressure common rail, giving the system proven durability under high-load, continuous-duty operation typical of commercial trucks, buses, and off-highway equipment.

For reliable long-term service, the injector should be operated exclusively with Ultra-Low Sulfur Diesel (ULSD), paired with regularly replaced OEM-spec fuel filters to prevent nozzle contamination. Periodic injector diagnostics and correct injection timing are recommended to maintain balanced cylinder performance, stable rail pressure, and full emissions compliance throughout the component's service life.
